Choose comparable Steam games you can defend
A familiar hit can explain your idea. A defensible comparison helps you decide what to do next.

That gives you plenty of possible references and very little help choosing which ones belong in your pitch or design review. The figure is a tracker snapshot, not a count of your direct competitors.
Choose comparable games by the decision they can inform. Check the base-game identity, the mechanic and the relevant release event. Then record why each candidate is included, excluded or still unknown.
A familiar hit can explain your idea quickly. Its price or lifetime review count may answer a different question. The three checks below use public Steam examples to show where a convincing comparison can come apart.
Give every comparison a job
Write the decision first: “We need examples of games where building a deck drives repeated runs, so we can compare how they introduce card choices.” Now you have a player activity to inspect and a reason to inspect it.
An older game can be a useful design reference. A recent-release benchmark needs a defined launch period. A price comparison also needs a region, currency and price type. Keep those research jobs separate.
Steam base games with official descriptions supporting core deck construction; any release year or stage. A narrower variant adds a full release during 2020–2025. These rules serve this example, not a universal genre definition.
Use tags and recommendations to discover candidates, then verify each one. If studio size matters, source it separately: none of these store-page checks establishes a team’s budget or headcount.
Using AI to build your comparable shortlist
Use AI to suggest candidates after you have written the comparison rule. Specify the player activity, platform, content type and release window; add price or team-size constraints only when you can verify them. Ask what makes each suggestion relevant to your decision.
Help me find candidates for this decision: [decision]. Apply these criteria: [mechanic, platform, content type, release stage and date range]. Return a shortlist with each game's title, official Steam URL, rationale, supporting source and unresolved questions. Separate evidence from inference. Flag criteria that are unsupported and explain exclusions. If you cannot check a source, say so; do not invent links or fill gaps.
Treat the output as leads. Open every source and confirm it supports the stated reason. Run the identity, mechanic and release checks below, including whether a link resolves to a base game. Keep unknowns and exclusions in your research notes, with the next check recorded. You decide which candidates earn inclusion; an AI-generated list does not establish a representative market sample.
Three checks before a game earns its place
A familiar name can lead to the wrong product
Verified: Slay the Spire is Steam app 646570. App 877620 is its soundtrack, whose listing explicitly excludes the base game. The names overlap; the products do not.
Open the store link before copying a metric. Match the title, developer and content type. Keep demos, DLC, soundtracks and bundles in separate rows when they are relevant to your question.
Save the public app ID and resolved URL. If two links reach one base-game page, investigate the duplicate; if a link redirects, retain that resolution note. A title match alone is insufficient.
Decision: include the base-game record in a design comparison; exclude the soundtrack as “different content type.” This says nothing about either product’s quality.
Check what the player actually does
Verified: Valve’s tag documentation says developers, players and moderators can apply tags. Only the top 20 are visible to users, and their weights can change. Tags are useful leads with a display limit.
Slay the Spire’s description explicitly presents deck construction across runs. Final Knight’s page describes a party-style roguelike beat ’em up, action RPG combat and party building. That does not establish our core deckbuilding requirement.
Interpretation: include Slay the Spire. Mark Final Knight Unknown for this narrow mechanic and hold it out of calculations. It may suit a different research question.
Define the activity your rule requires, then attach supporting official description or manual evidence. An absent visible tag does not prove a tag never existed. An unresolved row should name the next check: “Find evidence of deck construction as a central player activity.”
Two correct dates can produce two different cohorts
Verified: Against the Storm’s Steam page lists Early Access on 1 November 2022 and full release on 8 December 2023. Choose the event before assigning the game to a year.
Use for an Early Access launch cohort.
Use for a full-release cohort.
The title passes a “Steam full releases in 2023” date rule and fails an “Early Access launches in 2023” rule. Its city-building mechanics still need to fit the research question.
Final Knight remains labeled Early Access, with an EA date of 12 January 2025. That date cannot stand in for an unverified full release. Likewise, a lifetime review total read today cannot stand in for a first-month result: name the launch event and observation age.
Show what changes when the rule changes
Apply three increasingly narrow rules to the same four records. A admits base games; B adds core deckbuilding; C also requires full release during 2020–2025. Every condition in the chosen column must pass.
| Candidate / evidence | A · Base game | B · Deckbuilding | C · Recent full release |
|---|---|---|---|
| Slay the Spire 646570 · Mega Crit | ✓ IncludedBase game. | ✓ IncludedDeck construction is explicit. | × Excluded23 Jan 2019 falls outside 2020–2025. |
| Slay the Spire – Soundtrack 877620 · Mega Crit Games | × ExcludedSoundtrack. | × ExcludedFails base-game rule. | × ExcludedFails base-game rule. |
| Final Knight 2072980 · 2oclocksoft | ✓ IncludedEarly Access base game. | ? UnknownCore deck construction unverified. | × ExcludedFull-release rule fails; mechanic unresolved. |
| Against the Storm 1336490 · Eremite Games | ✓ IncludedBase game. | × ExcludedCity-building case. | × Excluded2023 date passes; deckbuilding rule fails. |
What changed: narrower rules changed membership without changing the games. None of these selected records passes C. This is a teaching set, not an exhaustive search or evidence about the size of the deckbuilder market.
Keep an older title in your design-reference list if it helps. Do not quietly relax a recent-release rule to retain it in a benchmark. In a pitch, explain each comparison’s job: the mechanic it illuminates, the audience assumption it tests or the release condition it shares.
Keep the exclusions where a reviewer can see them
A useful comparison log preserves the candidate, evidence and decision together. Exclusion adds a reason; it does not erase a row.
| Research field | What to record |
|---|---|
| Identity | Title, Steam app ID, resolved official URL, developer and content type; aliases or redirects where relevant. |
| Mechanic evidence | A short paraphrase and primary-source link supporting the required player activity. |
| Release event | Platform; separate Early Access and full-release dates. Use Unknown when unverified. |
| Membership | Rule version; Included, Excluded or Unknown; reason and next check. |
| Provenance | Check date, researcher and reviewer. Preserve earlier decisions when evidence changes. |
Resolve duplicates, set unresolved cases aside and freeze a dated list before calculating. Ask another person to check consequential inclusions and exclusions. Report known, unknown and excluded records separately in any later distribution.
Also inspect how you found the candidates. Memorable games make a convenient starting list; a review-count floor removes less-reviewed titles by construction. Neither method establishes a typical outcome for all developers. Pricing, sales and demand need their own evidence after membership is settled.
