I just went from an original iPhone to the new 3GS. I'm looking for some really good games, graphically intensive games, games that would have made my original explode. Ha ha. And if there's any good 3GS "exclusives out there too. (I came home with a 50 dollar iTunes card so load me up guys)
10 games that play better on iPhone 3GS http://www.pocketgamer.co.uk/r/iPhone/Top+10+iPhone+charts/feature.asp?c=14071 See also this forum: http://forums.toucharcade.com/showthread.php?threadid=28498
Here's a game that would send my old iPhone into spasms but plays beautifully on the 3Gs: Pirate Wings. It wasn't designed for the 3Gs (in fact, it came out months before it was even announced) but the developers got a little too ambitious and made a console style flying game that was virtually unplayable on first and second gen devices. You should be able pick it up for .99, which is a terrific bargain. I would also check out Iron Fist Boxing. It's playable on a 3G, but on a 3Gs it just blows you away graphically. Then, of course, there are games like Ravensword and Driver that play well enough on older gen devices but throw in a bunch of extra goodies for 3Gs owners. I'm sure others will chime in with more options.
Oh those links will be a huge help. Thanks a bunch. also thanks for not being a dick about it. 3GS is too few letters to search for. Thanks
