Honestly, I don't think it's in any danger of dying. It might look that way because the majority of people you see discussing things on the forum aren't talking about how much they like the game, or how well-done it is, or how excited they are for so-and-so update/patch...they're talking about how unrealistic it is. Or how arcade-ey the game's become and how they'll never touch it again. Or screaming for the developers to be lynched until they fix random collections of various bugs & things like that.
I play the game. I enjoy the game - greatly.
I don't see any fewer players than there were at the start.
And I'm not getting myself upset every time I'm reminded that there's more than one submachine gunner per map. You either enjoy it or you don't, but with a franchise like RO, where the fans are about as "hardcore" & loyal as you can get, it seems like a lot of people forget that the goal is to have fun...because they're disappointed with how the game turned out (as in contrary to their pre-launch expectations).
