Hey dude,
Yeah, SH3+GWX is awesome, really love it as well. But the 3D damage in SH4 won me over (for now), nothing like blowing a gaping hole in a freighter. Just a sucker for eyecandy I guess. That, and I have a thing with the Pacific. Guess it's because I played P.T.O 1&2 an awfull lot in the past.
You never noticed the sun halo disappearing? Just a detail, but I can't stand the idea of missing some visuals... Geez, I really am a sucker for eyecandy, aren't I?
Btw; E6750, P35 MoBo, Kingston memory, 8800GTS... I'd say we have the same taste.
