I just finished DMC 3 for the first time and I have to be honest, I really didn't like it. The enemy design is not enjoyable whatsoever. There are the basic reaper guys who are mostly fun, maybe a bit too easy, to beat up. Then everything else is an annoying flying enemy, an enemy who does not get stunned at all or has to be fought a very specific way, obnoxious flying niggers who have to be shot a thousand times before they turn to stone OR have to have their wings broken off before you can hit them, the spider guys who just eat hits by the dozen, and the statues that are just obnoxious and not visually interesting at all to wail on.
The game is also very ugly, I don't just mean texture work or anything like that, it just totally lacks color and has filters slapped all over it. Environments themselves are kind of cool though.
Maybe the game becomes better if you use the style switcher mod. I don't know. But anyone saying this is the best game in the series is tripping hardcore.
