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
It has never been cheaper than $0.99. That was June 2019. 66 discounts in the 14 years on record. They run about 80 percent off, roughly 8 weeks apart. Today it is at full price. The last sale was about 13 weeks ago, and on this game's rhythm the next one tends to arrive within 8 weeks.
On value it sits in the top 1 percent of its genre. It is pricier than 71 percent of its genre, and the best reviewed. The nearest things to it, Portal ($9.99, scores 83) and Suicide Guy ($5.99, scores 74), are both worse buys on this math.
Of the 800 Steam-purchase reviews this site sampled, 12 come from buyers who refunded the game, sampled from reviews written August 2025 to September 2026. Inside the two-hour refund window, 94 percent of the 18,341 reviews written there were positive, against 99 percent overall, and those are 5 percent of everything written about it. It sells extras on top of the sticker price (time-limited); the score docks it lightly for that.
HowLongToBeat players log 8.5 hours as a typical playtime, and completionists log 23, 2.6 times as much.
15 years after release it still had 2.0K people in it at once.
It carries Valve's Deck Verified rating and runs 8.5 hours, about as long as a handheld game wants to be.

What players say
this reminded me why i liked playing video games in the first place. and game itself aside, THAT VOICE ACTING AND MUSIC!!! this game is a treasure chest.
*SPOILERS* This game is the best story game anybody has or will ever play. It's so funny, cool, entertaining & story rich that I dont know where to start this review but I'll try my best. The Story is one of the strongest stories in any game I have played. You need some basic information from Portal 1 but when you know that stuff (& lets face it, you have probably played the first game & know that stuff) it's smooth...
It's ♥♥♥ portal 2 what do you want me to say. Portal 1 and Portal 2 is the greatest lesbian break up story of our modern times go play it the bundle is like 15$. Or get it on sale and then it's 5$ I suggest getting it on sale but only because I'm stingy as ♥♥♥♥. Portal 2 expands on portal 1 in every possible way like portal 1 is very good but portal 2 is a straight up Masterpiece of modern gaming. Stop reading the...

Portal 2 scores 91/100 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/620/portal-2The 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 10, price as of Sep 24.
