And that classic is: Virtual Pool by Celeris. A classic 3D pool game in the very late 1990's, it's super intuitive to use, and by far the best pool game on the iPhone, imo. What's even better, is that the devs are participating on the macrumours forums, to get ideas on how to improve it - very refreshing. Check it out.
I agree. A lot of people were complaining about it, but I honestly don't get why. I think it's a great game. I suck at it apparently, but it's a great game. I can't even get past the second person. I tried the free version of Vegas Pool Sharks and it looks and plays like a piece of crap in comparison.
