None There isn't any games currently that I feel would warrant that price tag. There are quite a few that could but they all seriously lack content and/or are full of bugs.
Spider, Jet Car Stunts, Hook Champ, Mecho Wars, provided they all had a little more content would be worthy of a $30-$20 price tag
None! I like small puzzle games like Implode or Bejeweled2. I like to play with my iPhone only for a few minutes and then do something else. This doesn't justify a higher price tag for me. I wouldn't use the app-store anymore, if I had to pay much higher prices than now.
Zenonia and hybrid can't compete in the ds environment! They are not in the same league with the countless awesome RPGs in the ds.
1. Battle for Wesnoth - graphics, content, story, depth are console quality (which I guess it already is, on the Computer, but a DS would work splendidly) 2. Starhogs - it is a perfect alternative to worms with tons of content as well. 3. Jules Vern's Return to Mysterious Island - huge game, gorgeous scenery, and has a deep story 4. 2xl ATV offroad, solid racing experience. I can't believe I got it for 0.99, it's daylight robbery! 5. G- by Soma, it is a BLAST. (probably have to look it up to get this joke)
DSi Ware perhaps? As for me, I think Jet Car Stunts, I would pay big bucks for that and I can even see it on something like Xbox Live or PSN if they up the graphics a little and add a bit more content.
Defence Chronicles The Quest Fargoal Labyrinth 2 Pathpix Pro Bobby Carrot Think there's more but this is the lot that comes to mind immerdiately
In my opinion, DS games are overly priced to begin with so there's not a game I'd pay more that $10 for except maybe Chinatown Wars and some of Gameloft's games.
For now: Defender Chronicles: Countless hours on this one, beautiful graphics, endless entertainment if you like grinding and getting the best equipment GTA: CTW: However, this was a port from the DS so I don't know if it still counts Ravensword: If this were expanded and provided more RPG elements along with more customization
