Fifa 10 isn't really my cup of tea, but I got it anyway. I think it has some multi-touch problems though (I've already turned off accelerometer and using D-pad) or sensitivity issues with the A / B buttons as they tend to not work well unless I stop using D-pad and focus on them.
Also annoyingly in my attempts to fumble around trying to find the spot to activate the A / B buttons I tend to hit the Home softkey instead (as they're fixed near bottom-left corner, and the game won't invert when I flip the Streak around), which kills the app.
I noticed we only get 15 minutes now in order to qualify for an absolute refund on apps from the Market (thought it used to be 24 hours?), which isn't even enough time IMO to ascertain that a compatibility issue like this really does make the app unusable. If I'd paid more for it, I would probably return it and say I want a refund, but at this price I can't be bothered even if I think the reality of EA acknowleding and fixing this is likely nil.
NFS:Shift is a blast though, and whilst I've seen some games behave somewhat erratically when having to control them using accelerometers for steering/control, this one works very well.
That makes it the one and only game I would willingly play on the Streak (normally I'm just not into the mobile gaming thing).
