I checked out Need for Speed Shift demo on my Galaxy S. Very nice game I must admit. Nice graphics and no slow down whatsoever on our Galaxy S's. Runs very smooth. Just take a look at the video of the demo and the screenshots below I took. Amazing graphics.
The demo itself is short and only contains one car and one track.
I'll be buying this on when the full version is released. Not sure when the Need for Speed Shift release date is, it was meant to be last month but has been delayed?
