I hope both turn out well we really need some good shooters this year besides the typical crap they will be releasing.
MIght sound like a weird attitude but personally i hope one blows the other away, at least from a multiplayer perspective.
the online playercount of PC shooters, especially niche ones, (unlike the mainstream titles like cod/cs/bf) doesn't seem to be so strong anymore, with decent games not getting the playerbase they deserve.
Asides from the evr increasing strength + popularity of console titles, a good reason is probably due to players being spread thinly across a what is now a vast number of pretty decent titles.
So from the point of view of building a strong playerbase I'd rather see just one succeed at the expense of the other.
But as the unknown quantity i suspect it will be either the fresh brilliance or dire failure of OF2 that determines the winner -
if there is to be one.
