What's the damn pont of disabling the save feature?
I hate it when they go cheap on demos- like if they only give you the tiniest taste, you will be begging for more.
Put out a solid demo, like Battlefield 1942 or Unreal Tournament 2004, that's un-watered down and impressive in it's own right.
That's what makes people go from demo to purchase.
Eh... not a chance in hell I would buy this game regardless of the demo anyways.
