Multiplayer games

I need help find mulitplayer games for the DS that are actually good. My girlfriend and I love playing games, and we've just beaten Kirby Superstar Ultra and damn. That game was great.
So please. Help a gamer out. ;D

If you're both using flash carts, then grab Soma Bringer and the translation patch for it. (That is, if you haven't played it already.)Thought of a couple more. Mario PartyDS. Then there's also Mario Kart. I'm sure others will have more suggestions then what I've already provided, but it's a start. :)

Thank you. Yes, we both have R4is. Even though hers is newer and better than mine... -_-*
Anyways, I haven't heard of Soma Bringer. I'll check into it. These are some games we've played and beaten so far.
Kirby
Pokemon
Mario Kart
Bleach Dark Souls
Prey the Stars
Zelda Phantom Hourglass
Legendary Starfy
Metroid Prime Hunters
Mortal Kombat
CoD World at War
Clash King
Kingdom Hearts 358/2
Moero Nekketsu
Dragon Ball Z
Tenchu Dark Secret
Transformers
Animal Boxing
Core

No problem. Always glad to help a fellow gamer out. :)But if I can think of anymore, I'll let you know.

Soma Bringer looks really good. I read it up on wiki and I liked it. Thank you for telling me.
If we both like it we should be set for awhile. Although it would be good to have games ready on the side.
I'm gonna need my friend to do the english patch thing for me tomorrow though. He hasn't taught me how to do that stuff yet.
Thanks again.
