Well, I'd chim in with: Reign of Swords - a really massive and well-done turn-based tactics game. Love it to pieces. Glyder - a beautiful and relaxing motorless flight game, with some challenge. Really great production values. iSkydive! - another take on motorless flight (or fall in this case), very challenging and score-oriented. Also quite pretty. Stich'em Words - a nice word game with a twist of charade addition. Also, occasional bonus levels with "brain" type gameplay. Quite fun, IMHO.
TOUCH SKI 3d. that is a fantastic game with loads in it. dino smash online is great too. They are my latest 79c purchases.
