It's alright so far. I didn't get to do much with it last night because I didn't start playing until late and I had to go through all of Tom Nook's obligitory "your my bitch now" tasks... Once I got throught those I was able to start playing a little bit (despite all the towns people of Cock Bloc going to bed).
The game does feel a bit limited though. Yes, I know it's a DS title, but I'd like to be about to use more than 8 characters in both my town and user name. I had to shorten "Extra Zero" to regular "Zero" and my town name from "Cock Block" to "CockBloc"... Also, the fact that not a single NES game is included kinda irks me... Yes, it IS a DS game, but it's either a 1 gig or 512 MB cart! NES games were like 15-200 KB in size, so I don't see why they couldn't atleast thrown in Balloon Fight or Excitebike--those were TINY games.
I still need to make my own textures and stuff, I've already played with making a town tune and I'll probably try WiFi mode tonight after I get some friend codes, so I'll post updated impressions then.
