21. Sim City

Sim City obviously would play much better on a larger screen, and the game's complicated data wouldn't be so squished.
22. Super Monkey Ball

Tilt-based games are sometimes hard to control on the iPhone and iPod Touch. While graduating to a large screen wouldn't necessarily make things easier, there's something about Super Monkey Ball that seems like a perfect fit for larger-scale controls.
23. Sims 3

The Sims feels a little played out at this point, but the iPhone version still did pretty well--and moving to a bigger screen would be nice.
24. Touch Grind

The original version of this cult iPhone/iPod Touch hit used your fingers to pull off tricks--on a big screen, you could even develop a title with multiple boards and two-handed/multiplayer action.
25. Wooden Labyrinth

There are already several takes on the classic tilting board game on the App Store, but an accelerometer-controlled version on a giant screen could finally be a true recreation of the larger-scale game we played in our basement in the 80s.
26. Plants vs. Zombies

We've been waiting for the App Store release of PopCap's monstrously addictive tower defense variant for months, but the iPad would be an even better way of matching the feel of the PC/Mac original.
27. Settlers of Catan

Cheap ports of classic strategy games abound in the App Store, but few are multiplayer-friendly. Updating a new version of Klaus Teuber's brilliant board game would allow for a much more board-game-like feel, and a multiplayer mode closer to the one on Xbox Live Arcade.
28. Quick Hit Football

While Madden and NFL 2010 already aim to provide console-style football gaming on a handheld, free multiplayer casual games like Quick Hit Football take an armchair-quarterback top-down approach to play calling. Porting this to the iPad would be a perfect way to casually play tablet pigskin.
29. Grand Theft Auto: Chinatown Wars

GTA: Chinatown Wars has been around the block, carrying its retro top-down gaming to the Nintendo DS, PSP and iPhone/iPod Touch. On the iPad, however, one could theoretically keep heads-up maps side by side with the action, or whole new submenus and screens for managing phone calls and e-mails while driving.
30. Peggle

We'll admit it, we're still completely addicted to Peggle. The iPhone and iPod Touch version is admirable, but it squeezes a lot into a small space. Amping the graphics and animation in a full version would be fantastic.
