Wifi...Starfox, Mario Kart, Metroid, and Custom Robo.

FF3 is just great to have too. New Super Mario Bros and Super Mario 64 DS are awesome offline as well.

I kinda liked the on foot missions. Now, if aiming was a lot easier (Which on the Wii it would be) I think they could be a lot of fun. They'll do a Starfox eventually, though. It'll probably be next year until we see it, but I dunno.

I'm buying both, so Spiderman 3.

It comes out earlier. >.>
 

3D - Twilight Princess

2D - The original, maybe. It may not be the best story telling but it's incredibly intense gameplay wise, what with the 'finding everything for yourself' thing. A Link to the Past was intense as well, and if it's not first, then it's definately second.

Between friends, in the lobby between games. 

I really liked Star Fox Command. Custom Robo is starting to get up there for me, just because the 3D fighting is pretty awesome. 

I'll tell you why Mario Party would be hard to do on DS.

You remember those online gems you sometimes run into? The one's that leave when the going get's tough? Now, Mario Party games can run for hours. Also, If someone were to leave mid-game it could really screw things up. (Like Starfox!)

Also, most of the fun comes from playing real people in Mario Party. Unless it had single card play, it could get mightily expensive to have lots of people playing locally. The most logical situation is to find a few people online that you could play with regularly.

Granted, I'd love it. The DS itself has the power. I'm more concerned about people. =P

Smash Bros. would be cool as well, but I think Nintendo has their hands tied right now with Brawl.

Megaman as well, but 3D style. F-Zero too.

The graphics aren't even that bad. Maybe in comparison to some of today's stuff, but they're still pretty nice.

I don't think they would do it. What I would like to see is if they try and make the motion a lot better for sword fighting, like 1 to 1 motion. It'd be pretty intense to play like that.
