KoToR isn't long enough?
I just looked at my purchased games - some great standouts
The Room 1 & 2 - great puzzles.
Costume Quest - lighthearted RPG
Golden Trails 1 & 2 - nice HOGs without horror theme. Sometimes it feels like all hidden object games are horror stories. These are not and they are fun
Baldur's Gate 1 & 2 - hey you wanted more than KoToR!
My Kingdom for the Princess 1, 2, or 3 - nice time management games
Galaxy on Fire 1 & 2 - great space games
Aralon: Swort and Shadow - as close to the Elder Scrolls as you can get on iOS
Crux - great crossword app. Download a few months of crosswords and you will be set!
