Plunderland is 66% off now, for 99cents! First time it ever dropped price (from 2.99) according to appshopper: http://appshopper.com/games/plunderland I just bought it, hope it's fun. Got lots of good reviews and has high ratings. Also it's universal, which is good. TA Review: http://toucharcade.com/2010/07/23/plunderland-review-surrender-the-booty/
That's honestly half the fun. I bought the game when my accelerometer was completely broken on my second gen. In other words, I bought a game I didn't know I couldn't even play. When I got my 4th gen., I had a great time with it. It definitely deserved all the attention and sales it got back then.
OK, I've played Plunderland a good bit since buying it the other day. Backtothis is indeed correct, it IS fun! Really great and unique game, and worth owning for every iOS gamer. Get it!
