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 $4.79, set in June 2019. It has been discounted 20 times in the 12 years tracked here, typically at 67 percent off, with about 6 weeks between sales.

It is pricier than 97 percent of its genre, and less well reviewed than 78 percent. On the same math Halo Wars: Definitive Edition ($19.99, scores 85) and Planetary Annihilation: TITANS ($29.99, scores 63) are the better buys, and they are the games it most resembles.

The press liked it more than its buyers did, 77 against 68 percent.

This site sampled 459 of its Steam-purchase reviews; 4 were written by buyers who refunded it, sampled from reviews written April 2020 to September 2026. Inside the two-hour refund window, 35 percent of the 265 reviews written there were positive, against 68 percent overall, and those are 10 percent of everything written about it.

What players say

Such a GREAT GAME. Mixed review is BS. Damn shame it didn't get more traction. Wish there would be a follow up 2. Same concept and everything. Could have been an sc2 type predecessor sigh. If anyone wants to play ping me.

I liked this game. I didnt finish the campaign bc my hand was traumatazed, but I wanted to. Its not as good as CnC3 but better than CnC4 :)) Good game for RTS fans.

Can't play with dual screens unless you want both your monitors to power cycle for 30 seconds every time you minimize

Player reviews from Steam: the most helpful all-time, plus the newest that clear the same quality bar, with the hours each player had put in when they wrote it. The mix of Recommended and Not recommended follows the game's Steam ratio. Rotates daily. Opinions are theirs.

[![BANG Score](https://steambangers.com/api/badge/290790)](https://steambangers.com/game/290790/grey-goo)

The 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 20, price as of Sep 22.

A number here look wrong? Tell me what it got wrong and I will look at the inputs behind it.
