Need help picking a good iPhone game?

[Brendan]

I have decided I am willing to buy a game on the app store for my iPhone and I was just wondering if anyone could hit me up with some suggestions, at the momment I am thinking things like "the sims 3" or "gta china town wars" or maybe even "simcity" so I was wondering if anyone could give me a bit of help here? Are any of the ones I have said good? or is there other games I should be giving an eye to? Thanks ahead of time
