Every ds game worth buying

I've only beaten Contra 3 & 4, so I don't know about the first 2. While Contra 4 has 9 stages compared to Contra 3's 6, Contra 4's stages are mostly shorter. I think it is a bit longer overall though (and harder). Contra 4 seems to give you extra lives more often though. When I play through the game I often (at least once every playthrough) have moments where I'll screw up really badly and lose 3 or so lives in the span of 20 seconds, but still end up finishing the game with about 10 or so lives.

Where's the love for Radiant Historia? It's the JRPG that answers nearly every complaint about JRPGs. Meaningful choices? Got 'em. Linear gameplay? Not with the ability to jump through time. Girly characters? Rosche is so manly he makes Chuck Norris look like Richard Simmons.

9 hours 9 doors 9 persons. it's a visual novel but it's got a fantastic story and you need to play it over and over t get the full story.

yoshi's island 2. the sequel to one of the best platformers ever. need i say more?

professor layton games.great puzzles and it's the sort of game you can play for 5 minutes or 5 hours.

Infinite Space

this time 100, infinite space is seriously a brilliant game. but sadly almost impossible to find. online is probably the only place you'll find it.
metroid hunter is probably the only good FPS on DS

Pokemon Mystery Dungeon.Preferably Explorers of Sky.
Final Fantasy Tactics A2
FF Crystal chronicles Echos of time.

Try Dragon Quest 9,it is more community oriented but it makes for a pretty good rpg.Also,if you don't mind good game but very short try the new Golden Sun.
The Final Fantasy Tactics Grimoire of the Rift was good and I seriously recommend heartgold to you

Professor Layton series if you like puzzles, and only puzzles. The games are just one puzzle after another, with a story (with, I must say, very good cutscenes) that doesn't really connect one puzzle to the other.

Chrono Trigger, Final Fantasy IV, Castlevania: Dawn of Sorrow, New Super Mario Brothers, and Brain Age 2 are what see the most use on my DS. Your mileage may vary.
