Well, color me impressed. I really like how the screens look, and though I wouldn't be too interested in any rehashed zones most of the time, Aquatic Ruin I can live with. Especially this screen, it just looks fantastic to me.
I'm interested in seeing how the online co-op turns out, but if it works well, that will give me a lot more reason to replay Ep.2
As for the complaints about only 4 zones, it's not really that surprising. Episode 1 was short, as was Colors and Generations. If it's like Episode 1, we'll be getting 3 acts per zone, so that's not too bad, I suppose. Still would've liked more, but oh well.
