So, you've got an iPad sitting around. What games should you play on it? Well...there are a ton to choose from. And thanks to some aggressive holiday sales, some of these games are available for a steal.

And just what does make a good iPad game? We debated it for a while, and...well, for each person that decision will vary. Some of these are board games. Some are like interactive art. Others are free(ish) and ridiculously addictive. In other words, it's subjective. Most of these play on iPhones, too, but for a lot of the ones on this list you're better off playing on a larger iPad screen.

With that in mind, here are our current favorites, displayed in alphabetical order. Feel free to sound off with your own picks (or criticize our choices). There's no way to catch all the games out there, but you probably won't regret trying these.
