There's no such thing as "The Best DS game of all time". But in terms of gameplay, I would pick TWEWY. But I thought it was My Little Pony?
I completed The World Ends With You.I still think DQ9 is better but TWEWY has quite and envolving story.
DQ9 was nice, but felt like just another cog in a wheel. A better cog, sure, but it isn't outstanding from the crowd enough to earn my aye. I really like the Ace Attorney series, though it technically isn't 100% DS (Being GBA remade and all that.) The story was good, the puzzles entertaining, and the characters were strong and unique. Of course, it's got no adventure elements at all, so it's not everyone's cup of tea.
When I heard, I saw someone saying it was going to be on the iPhone or something like that. What platform is it for anyway?
3DS. But it's only announced for Japan so far. :S Oh, I can't chose my favorite DS game. I do love Advance Wars: Dual Strike~ and The World Ends With~ You quite a lot.
D:| Now I have to buy it too. And I thought I'll actually be able to skip out on ONE nintendo handheld... >_>
Ghost Trick might change my opinion, but I enjoyed the Ace Attorney series the most. Next to that would probably be Pokemon or Legend of Zelda Spirit Tracks.
Its a battle between The world ends with you or Chrono trigger. Both games are amazing. I played Dragon quest 9, although I didn't really like it.
