I never bought it at release due to the fact that I couldn't get my hands on a physical copy and I can't still do that.
How is the game bad? Is it just all the bugs, glitches, and unstable gameplay?
I still remember seeing a game-play video for this game post release, god if you thought hip-firing MGs were bad in RO2...
Do keep in mind that in general not everyone is looking for a sim level game experience that ArmA related titles give. Just like how you dislike the current state of RO2, some dislike the ArmA series.
