Moon is quite entertaining and very technically proficient with some of the smoothest graphics you've seen on the DS. Though to be had, the game never truly pushes past the interesting marker. You'll get more weapons and continue to look out for artifacts and weapon/health upgrades, though they could have worked on the story a bit more, as well as the enemy types. Still a fun game nonetheless, but a little bare in the actual content. Not sure about CoD on the DS.
if you're in the mood to do something different, GTA: Chinatown Wars got extremely high praise and everyone I know that played it actually found it quite addicting. The new Zelda game is quite fun and really picks up on how to create dramatic cutscenes, the Phoenix Wright games(that I've recently gotten my hands on the first title) is actually rather fun if you don't mind something different. I won't stop emphasizing the unique presentation that
Rhythm Heaven produces, and
Space Invaders Extreme is actually one of the weirdest, but funnest shooters I've seen to date since there's both background music and sound effect synchronization to make for a Rez-esque style music set-up.
Henry Hatsworth I've heard is quite a fun platforming/puzzle game, Professor Layton titles are quite fun, If you liked first Generation Sonic titles,
Sonic Rush(
Adventure included) is a very nice throwback of the original run right platformer with much more speed, If you were ever a fan of Phantasy Star Online, they ended up releasing Phantasy Star 0. There's much more, though I'll just stop there for now.
