What drives the score
How to read this
Every input gets a grade, S to D, read from the buyer's side. The score is multiplicative, so an input only counts as raising when it sits near the top of its own scale. Anything with real room left is holding the score back, because that room is the gap to 100. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. The exact weights stay secret.
The value story
The lowest price on record is $0.99, set in March 2025. It has been discounted 54 times in the 11 years tracked here, typically at 70 percent off, with about 6 weeks between sales. Today it is at full price. The last sale was about 3 weeks ago, and on this game's rhythm the next one tends to arrive within 6 weeks.
Value puts it in the top 1 percent of the games it competes with. It is better reviewed than 99 percent of its genre. Among the games that feel like it, DELTARUNE ($24.99, scores 95) beats it on value, while it beats West of Loathing ($10.99, scores 87).
On this data it would still be a BANGER at $11.38. It costs $9.99.

Inside the two-hour refund window, 86 percent of the 17,032 reviews written there were positive, against 97 percent overall, and those are 6 percent of everything written about it.

What players say
Even as someone who isn't the biggest fan of RPGs, even as someone who wasn't expecting much out of this game, I've come to really appreciate it. There's an air of sincerity and whimsy that I haven't found anywhere else. In the world we live in now, it feels hard to keep going. hard to feel like anything we do means anything. Despite that, this game still made me feel something. This game still managed to make me, a...
Undertale had been one of, if not the first ever, game to leave a lasting impression on me. For years, this game has shaped who I am as a person and how I look at different situations that pop up in my day to day life, and that is something no one could ever take away from me. This game is the embodiment of reflection, decision making and moral compass developer. And even though the fanbase might be a bit.. weird...

Undertale scores 88/100 on the BANG Score (a BANGER). The BANG Score rates what a game is worth for the money. Via Steam BANGERS. https://steambangers.com/game/391540/undertaleThe BANG Score is one number for value, 0 to 100: price against how it reviews and how long it was built to be. It answers the money question and stops there; whether the game is for you is still your call.
Reviews set the ceiling and price moves you inside it, so a cheap game that reviews badly cannot climb. Ratings from few reviewers are shrunk toward the middle, so 100 percent from nine people does not outrank 96 percent from ninety thousand. Length comes from HowLongToBeat where it can be matched, measured against a per-genre floor so a five-hour narrative game is judged against other narrative games rather than against a sixty-hour RPG. Where no verified length exists the score says so and carries a dock, because the biggest input is then a guess. The full method, including where it is weak → Steam reviews as of Sep 11, price as of Sep 24.
