Today was the start of the 2010 E3 and unlike last year, there are tons of great iPhone and iPad games being show.

Ultimate Spider-Man: Total Mayhem – Why save the best for last, let’s just start off with the best thing I’ve seen so far, Ultimate Spider-Man: Total Mayhem. This new game from Gameloft is based on the Spider-Man comics, not the movies. And the game shows it’s comic roots. While the game is still pretty early, it’s showing really great promise. No release date yet, but expect it fairly soon. Take a look at the trailer released today by Gameloft.

Sonic the Hedgehog 4 Episode 1 – Next up, that speedy blue hedgehog turns up again in Sonic The Hedgehog 4 Episode 1 for the iPhone. This, unlike the previous Sonic for the iPhone is an all new game with new graphics designed for the iPhone, not an emulated classic. The game overall looked well defined, bright, and very speedy.

Dungeon Hunter II – Another Gameloft title caught my eye today as well, this sequel dungeon game looked amazing on a demo 3GS with great lighting effects and 3D graphics. Dungeon Hunter II should be hitting the app store soon. While I only had a little time with it I was really impressed with the lighting effects and the smooth gameplay.

Zombie Wonderland – Next up, zombies and more zombies. Chillingo had a few game developers to show off. Among them two vastly different, but good, zombie games. Zombie Wonderland is a sort of time management defense game. Your job is to guard the building you are in from the approaching zombies. You do this by tapping the zombies to shoot them, boarding up windows, and placing automatic machine guns. If the zombies get inside, you have to clean up their left behind goo before time runs out — see, time management! Zombie Wonderland is available now for the iPhone and iPod Touch, and coming soon for the iPad.

Oddly, two of the largest iPhone game producing companies, EA and Activision, were not showing any new iPhone or iPad games. Very odd considering the size of the two companies.
