only reason would be if you dont have a goodspec machine .. i agree should have been ported over ..mgs2 i played a while ago looks extremly sharp and the possibilitys of anti aliasing x16 is just mouth watering .. is their a specific reason it wasnt ported over..?
MGS2 was ported to PC as a consequence of being ported to XBOX.
Since they had to revisit the PS2 version and convert it to the Xbox, they basically had most of the work done already, hence creating the PC version was only a matter of optimising the game for multiple configurations.
However, since MGS2 sold average on XBOX, this lead KONAMI to abandon the Xbox ... and since they didn't have to make a PC-architecture MGS3 conversion that would work on Xbox, they didn't bother to make one for PC, since PC version usually sell even worse.
But in hindsight, I'll admit having a PC version of MGS3 would be awesome, as it would allow modding, hosting our own servers and "reviving" the classic MGO (because, while the new MGS4 MGO looks great, it doesn't have that Old-School 60s charm MGS3's MPO had).
