Need help deciding on a game

I just bought a 32GB iTouch today (birthday present to myself) and already downloaded NOVA since I'm hearing nothing but good things about it. I still have some money left over from a gift card on my account and it's enough for another game and maybe an app depending on how much cash is left over. Right now I'm trying to decide between getting Modern Combat: Sandstorm or HAWX. I've heard good things about Sandstorm and it seems to get mentioned every time someone talks about NOVA. However, I just got an FPS with NOVA and I love flight games so I'm leaning toward HAWX. Thing is, HAWX is more expensive and while it has good scores on the itunes store I haven't heard much about it. Is it good?So which would you guys suggest getting?oh yeah, and while it's not related to gaming I figure I'll ask it here anyway: Does the ''I am T-pain'' app work on 3rd generation ipod touches? I know the 2nd gen itouches had issues with the app due to lack of microphone, but since the 3rd gen itouches have mics will the app work fine now?Need help deciding on a game
I suggest HAWX. But if you like to play FPS game, maybe you should buy Modern Combat.Need help deciding on a game
One more thing. If you still can't decide, why don't you download the lite version. Then you can decide what's the best.
I have HAWX, its good, ~15 levels...~23 planes havent played modern combat...I have seen Top Gun (something like that) it looks like HAWX but has a 4/5 rating while HAWX has a 5/5 rating...but top gun is only$1.99
May I suggest Pandorum. While the movie sucked tha game was sweet , its like a mixture of old school and modern survival horror games its 4 bucks but well worth itAlso if you really like NOVA and have to choose between those two games you mentioned Sandstorm is pretti much the same level of fun
