Recommendations for great DS/GBA Rpgs?

I agree with Dizzy. Riviera had enjoyable but generic story with characters that I really liked and the battle system was a new twist.

I just got Lost Magic today and it's looking pretty good except for that time limit which is a problem for cautious players like me.

I find the Megaman Battle Network series enjoyable. I like 3 best myself compared to 1-4. I haven't played 5 yet so I can't tell you anything about that. 6 is coming out soon and I here it's going to be one of the best.

Atlus is bringing out Super Robot Wars some time this month if you like mechs and Fire Emblem styled gameplay. I've only played a translated rom of SRW3 and I liked it.

Atlus is also bringing out Summon Night this month as well. I've read it's an RPG where you create weapons and fight in a Tales of Phantasia styled combat.

You might also want to give the Castlevania games for a spin for platforming/RPG goodness with all those gothic castle settings.

Jam it back in, in the dark.
