First off, the 360 version looks absolutely fantastic, so i personally have no gripes with a direct console to pc port. I want to play that game.
HOWEVER, and here is the massive caveat:
It needs to be a GOOD port that actually shows a degree of respect for the pc community, rather than scraps from the table of the more profitable and larger console market.
Splinter Cell Double Agent for pc was a direct slap in the face for everyone who plays pc games and had supported the company. It was disdainful.
It came off as an indifferent attempt to milk a little more money out of the franchise with no thought whatsoever to the pc consumers, who ended up with a crappy looking, buggy port with shameless performance on systems whose video cards alone cost more than a 360. They would have been better off, in my opion, just cancelling the pc version.
So my real worry, and i would be eternally grateful for some validation or statements to the contrary from a Ubisoft representative, my worry is that R6 Vegas will be the same thing. As others have said, the writing is on the wall; no news updates, from the amount of information released it is clear the pc market is the redheaded stepchild here, unexplained delays, etc.
Please, ubisoft make this one work, optimized and give this game the release it should have on the pc.
Please to all who will buy this version, if they show this market segment the same amount of respect they did with Double Agent, join me in never purchasing another product from ubisoft.
