My most favorite iOS game in a long time:
http://www.deeploot.com
Deep Loot is free and comes with in-app purchases, but the good thing is that you just need to buy the in-app upgrade "coin-doubler" (3.59€) and you have a full game which makes a lot of fun for days and weeks. No need to buy anything else. Charming, addictive little game.
Peter Molyneux' Godus on the other hand is outright terrible on iPad (don't know about the PC version, but Steam gamers don't recommend it either). It looks gorgeous on iPad and has some very nice ideas (such as combining houses to villages), but it is unplayable without spending lots of in-app money. I deleted it after a few hours when I realized that the game basically stops if you don't pay an estimated 5€ per day to be able to continue anything, A game made by a (presumed) millionaire, crowdfunded by his old fans (not me, gladly)... For shame, Mr. Molyneux.
