Just picked up a DS about a week ago, and I'm looking for some great RPG's.

Basically what I'm looking for is length and depth, I don't like shallow games, and I don't like linear games either. I only have Pokemon Diamond as of now, so any help would be greatly appreciated, thanks!

Congratulations, the DS is a really good console I recommend you Mario & Luigi: Partners in time, TWEWY, and the FF and DQ remakes.

Length and depth, eh? But NOT linear? If you're a masochist with OCD, then Shiren the Wanderer is for you (it's a roguelike, though). Ditto for Eritrean Oddysey. For a more forgiving version of Shiren, there's the Pokemon Mystery Dungeon games (also roguelikes). Finally, there's Disgaea (Strategy RPG) and Final Fantasy Tactics Advance 2 (also a SRPG, and while I haven't personally played it yet it's received good reviews).

Haha, I guess I kinda am, you've sparked my interest. Linear games are fine as well, I'd just prefer something non-linear. I'm more concerned with the length and depth factor though. Thanks for your recommendations, I'll check some of them out.

Wait there's a Disgaea DS?

Don't get your hopes up too much though: it's essentially a port of the first game.

@Gobias: happy to help.

But seriously, make sure you know what you're getting into with Shiren. Technically, it's a turn-based RPG, but it's highly dependent on your learning how to react to situations. You will die, and often, and every time you do you'll go back to square one. And you won't get far if you don't stop to think about why you died, where you screwed up, and how to avoid making a similar mistake in the future. Most people find it frustrating, especially since you'll never encounter the exact same situation twice, but personally I love every second of it (hence the "masochist with OCD" comment...)

Sorry for babbling so much, though.
