Well... MBX lite is quite powerful... same goes for the non lite version. There are symbian based phones that make use of MBX (lite) for quite some time now (SE P1i, Nokia N82, Samsung i560, etc.) but there are just a few applications that even make use of it.
Playing games solely on a touch screen is not ideal IMO unless the game is designed around the touch screen scheme. A combination of both touch screen and actual buttons would be ideal but that's only possible on very recent UIQ and S60 versions.
In sort, only a few cellphones can be used effectively as gaming platforms at the moment and the lack of games which take advantage of the hardware is
THAT low that does not worth it.
