Phantasy Star 2 is on the app store for $1. If you liked the original, then you should get this one. It's a direct port.
Shining Force is also on the app store for $1. Direct port as well.
The Quest is decent, if you like some of the older Elder Scrolls games. It reminds me of Daggerfall. It costs $3 for the full version, but there is a lite version available.
