We know Toriyama's style works with 3D & with the DS with DQIX coming out. Enhanced remakes of DQIV-VI are also on the way here pretty quick, and show that even in a limited capacity, enhancing Toriyama's style is all good...& like stated, FFIII & FFIV did ATB style battles perfectly well in nice looking 3D.
Though I'm totally against people who say "I like 2D because it has it's charm to it"...You're living in a nostalgic fog. Worse graphics don't make for better games. It's like saying, "I like to watch old movies because of the grainy quality of the film & the lack of color really adds to everything"...While, an argument for color is plausible, unless you're going for soft-focus for a purpose, I'd rather actually be able to SEE what I'm LOOKING at. Just because there were a lot of good games that looked like shit (when everything looked more or less like shit) that doesn't mean good games now have to look like shit anymore just because it's easy.
I'm no graphics whore, mind you, but graphics are there to enhance gameplay. They aren't the sole reason to judge a game, that'd be like judging a game completely on it's music (if you like it so much, just get the album/MP3s).
BUT I don't mind CT DS being in 2D because I know (or "choose to believe" for you who want a Force Choke) that it's just testing the waters of the bountiful Chrono pool. We are Chrono Community. They will hear us roar. Like a mighty wave upon their shores. TO ARMS!!!
