OVrall, I'd still put PS2 ahead due to a far larger library. But I do put GC in the #2 spot, and it holds that spot solidly. X-Box has games out for it I like as well, but not enough to take over the other 2 spots. We'll see next fall when LIVe is fully underway.
In regards to Animal Crossing - I might pick it up tommorow. If not, pretty soon.
