Heh, had to be an AOLer...
I peronally can't wait for AC2, I just finished up a session of AC and I would love to see some online love. I don't really do much with online consoles since the Dreamcast, which I played a lot of. This is the game that would make me buy the modem or broadband adaptor, depending on my online situation. Being able to visit other people's towns would be great. I wonder if they would make this a peer-to-peer deal or have a completely server-side game. A P2P idea would be nice if a server just held town data, since it wouldn't have to completly depend on Nintendo supporting it. You could, say, post your name and town on the PGC forums and say you were going to be on around 7 EST, then the other peson could connect. Or maybe they could have plots of land in the online world for us to develop our town in, similar to 10six, the failed online shooter. Either way, it would be great.
I don't mind the graphics, I think they have a lot of style to them, they aren't boring like just plain shiney polys. I wouldn't say they should use the style for everything, but a light-hearted game like AC site nicely with it.
