These are some big games. Like, bigger than mobile games have a reputation for being. And they're free or on sale or just plain awesome!

Newly mobile: Guardians of Magic HD - The supremely playable (and one of this reviewer's personal favorites) casual adventure game Guardians of Magic: Amanda's Awakening has made the switch from downloadable title to reworked iPad release! Guardians of Magic is set up like many modern casual hidden object adventure games, though this one's focus is squarely on the adventure aspects. No hidden object scenes to contend with, just exploration, inventory puzzles, and a few mini-games. Great story, excellent puzzles, and a great fit for the touch screen.

On sale: Joe Danger Touch - Actually, we're telling a tiny fib with that headline. Not only is Joe Danger Touch on sale for 66% off, it also received a HUGE update that almost doubles the game's already well-stocked content! The new game mode Calendar Tour offers up a new level to play each day of the week, with more challenging tours as time goes by. If you're unfamiliar with Joe Danger Touch, you should make yourself familiar as soon as possible. Is it a great mobile racing game or the greatest mobile racing game? We think the answer is pretty obvious! (Joe Danger Touch review and download)

Free App of the Week: Angry Birds Star Wars - Each week on the iTunes App Store, Apple drops a single release down to the tasty price of "free". This week, that freebie is Angry Birds Star Wars HD. It's Angry Birds, it's Star Wars, and it's free. We're trying to find a downside to that whole situation, but it's just not coming to us. We will, however, say that you should totally shoot first and download the game while it's free.
