This this and this. The SaGa 2 DS soundtrack was total fail, it made me cry big tears. Big ridiculous tears.
Now if you're saying SaGa 3 is more fun than Chrono Trigger ... uh idk. Then again I haven't played SaGa 3 since I was like, 9 years old. So we'll see. The game actually shared some team members with the folks who made FF Mystic Quest for SNES (just check the graphic similarities, and it's the same music composers!). If they do this DS remake in a style that's all-together different from SaGa 2 DS, there's hope.
Now as for SaGa 1. That didn't get a DS remake. Why? I guess cuz they did it on WonderSwan color at some point, right? They should port that as a download-only item for the PSP and offer it for like $10. I'd buy that.
