The implementation of 3D in this game is weird as hell. At first I hated it, and to be honest, I still am not sure I like it, but I'm finding it to be useful for making the foreground look less cluttered. The small amount of depth and the blur help me focus on the action.
Still wish they had just done it like we were expecting -- with layering, which has already proven itself to be awesome in other games.
-no screen stretch when we go separate ways in multiplayer?
I know there are two seperate screens and all, but can you imagine playing with someone who's blitzing through the level whilst you're taking it slowly? wouldn't be very fun for the person behind.
I was thinking about this earlier, and I agree with you actually. It may seem a bit counterintuitive, but the idea of two people playing in the same game WITHOUT being forced to stick together just isn't a very good one. The lagging player may as well not be playing, to be honest.
The only way co-op could be implemented well with separate views for each player would be if stages were specially designed to require or encourage teamwork. Lacking that, I believe Nintendo made the correct decision here.
