The best of the Nintendo DS

That's a good list

Get the Sonic Rush games and Colors DS.

This image has everything I was going to add

I'd personally speak against Infinite Stratos. Game just bored me- and combat is a big part of the game. It's rock-paper-scissors with timing and needing better equipment to aid in that.
Which is a shame, since for the time it looks pretty good. Character sprites are gorgeous, even if you can tell what sci-fi actor they're based on.

FF Tactics A2 isn't much better. I don't know why, but I felt like I was just going through the seasons and never really progressing- and a lot of the new classes/races don't do anything that special without massive hindrances. You also have a limited roster- enough room for one of each class/race- if not for the many cameo characters from FF 12 that don't generate a new slot when they are added to the party.
Maybe I was grinding too hard for specific class things (like the ChocoKnights mount) or butt-hurt I'd have to lose characters I spent a lot of time grinding just to get Penn or Velo, but I'd say play the GBA one instead. A shame, since the DS one is superior in all other ways.

Also- never pay for games localized by NISA. Since you have a flash-kart, that's not an issue for you. Actually, since any DS games you pick up will be second hand or from the bargain bin- odds are it won't go to them anyhow.

Good story. I couldn't ask for a better ending, the ending really tied up all the loose ends in a satisfying way.

The 2 first sets of pokemon mystery dungeon are pretty good, other than that, I'd say is pretty much it. 90%+ of the ds's titles were shovelware or at least borderline, like GTA:CW.

Posting the only good DS game.

Fuck, what a terrible system, especially coming after the fantastic Gameboy Advance.

Great game though.

OP. Play Retro Game Challenge 1 & 2.
