For the car enthusiasts that want a more serious racing experience, Real Racing by Firemint should be your first stop in the App Store. With 30 real world cars, stunning visuals, and a variety of tracks, Real Racing is the closest you'll get to Forza on the iPad.
While not as cinematic as Call of Duty or Battlefield, Gameloft's Modern Combat series does a decent job at keeping up with the big boys. You'll shoot your way through a variety of set pieces in the campaign mode, then take your skills online to show off how good you are at getting headshots. There is even DLC in the form of extra multiplayer map packs.
One of the best third-person shooters on the iPad, Mad Finger's Shadow Gun has all the makings of an epic. You'll explore huge levels, fight your way past waves after waves of bad guys, and take down massive bosses. The latest update added an expansion pack, giving you another adventure once you finish the main storyline. No multiplayer in the iPad version quite yet, but chances are we'll see it in a future update.
Final Fantasy 3
The most expensive game on this list, Square-Enix's Final Fantasy 3 should need no introduction. Redone with 3D visuals, Final Fantasy 3's gameplay still holds up in an era where games like Skyrim and Mass Effect 3 take center stage. But it's still the classic, Japense role-palying game we've grown to love. Final Fantasy 3 may cost a lot more than most apps, but it is definitely worth the price of admission.
Another game series that most gamers should be familiar with is Sid Meier's Civilization. The turn based strategy game works extremely well on the iPad, allowing you to quickly get a game going or resume where you left off. You still have a wide variety of leaders you can choose to lead your civilization, everyone from Abraham Lincoln to Cleopatra, and you'll sink in a lot of hours leading your people to victory. Besides, what other game lets you have the Aztecs develop battleships?
Infinity Blade 2
