Even though Fallout(1 and 2) does have levels and experience points, the attribute selection is like you said, you choose your attributes at the beginning of the game, and you have them until the end. Everything is scaled 1-10, 1 being horrible and crippling, 10 being amazing, default is 5.
I too think aurora feint is excellent, the "the beginning" part of the title makes me even more excited, the detail page says they plan on making an MMO out of it. My favorite paid apps are Cro-Mag Rally and AquaForest.
I have an original, and chose not to upgrade. Just to warn you ahead of time, the voice AND data plans for the 3g cost 10 dollars more a month than on the original, the only advantage is faster internet(I'm not exactly sure how much faster, it might be worth it to you) and bigger hard-drive. However, the iPhone itself is, well, fucking awesome, even moreso with the new app store. If you want the best and the fastest iPhone, go for the new 3g, however, you could probably find an original for even cheaper.
