After trying the demo on both last night I can say:
They are very rough edged especially F1.
Didn't care for either in their current state.
Soda is slow moving.
Soda turns to radically at times. Rather play dirt bike Motoracer.
Soda looks like MTM.
Menu system on both were nice.
F1 was choppy to my standards, with flashing textures.
It obviously takes a lot to make a excellent racing game.
X-Car will be absorbing some hours in the next few days to get the car to
handle properly. If not back it goes. If I can figure out a proper setup then
this game will work for me.
Q.B.M.
