What drives the score

S is the best grade and D the weakest, judged as a buyer. ▲ raises the score, ▼ lowers it, ? is an input we do not have, • is a fact this genre's score does not use. How the grades work

Raising the score
Cost per hourFree
Price per hour of game. It moves the score inside the ceiling reviews set
MonetizationNone
Checked: no in-game purchases or loot boxes. That earns a small credit unless Steam lists in-app purchases
Holding it back
Reviews
Gates the score. Weak reviews cap it, and nothing reaches BANGER without strong ones
Reach750K+ owners
How many own it, by SteamSpy's estimate (an old snapshot). A free game has no price to weigh, so this is its value read
For context
RefundsFree
A free game cannot be refunded, so the label never applies
AI contentNone disclosed
From the developer's own Steam disclosure. No disclosure is not proof of none, so it does not move the score
