Do players value integrated Steam Input support or an in-game rebinding system more? I've always done in-game rebinding, since it works whether the game is played on Steam or not, and is "timeless" in theory.
@transmutrix For the same reason, I strongly prefer games that don't assume they'll only ever run on a store that will manage things like input devices for them. Especially when I look for those games DRM free on GOG, they will not have anything locked behind a Steam login anymore.
