I'm kinda bummed that I'm enjoying a 4+ years old game that got mixed reviews more than I could ever imagine enjoying Wreckfest. I mean, it has plenty of decent game modes (Domination, elevated derby rings where you have to knock out your opponents, tracks where you have to perform stunts / drifts, etc.), great soundtrack, very casual but enjoyable physics. Its presentation is not exactly what I'm looking for, but still it seems to be fun and diverse. I honestly can't see Wreckfest end up being that fun, I think it's trying to take itself too seriously.
Time will tell [I realize it's still (pre-)alpha], but I was hoping they'd go with FlatOut 1's direction - not too 'silly', but still arcade fun. I guess I was wrong. This announcement makes me all the more disappointed. It looks like they can't keep up with one project, and they still start working on another (which should be a part of Wreckfest in my opinion, but that's another story).
