Try Chrome. Its been hit by claims its too linear, dodgey AI and not open ended enough. But it is a blast with great graphics, sniping, huge outdoor environments 1 million+ plants and enough freedom to be fun - and it runs great on a geforce 3, paired with and AMD 1.4 Mhz processor at 1024*768. I'm an older gamer and avoid games pushed by hype-dom, if its fun I'll play if, its dull I stop. Don't be too harsh on Halo as it is two years+ old and still stacks up quite well, which is an achevement. Does anyone know why it needs such powerful PCs to do the eyecandy justice though? Is this the real reason why there was no PC version 2 years ago perhaps?
