I'd wait another month or 3, untill they release more patches that fix the moutians of bugs.
Aside from the bugs and poor performance, it's a very excellent game.
It's definately worth picking up for around $20 as VTM-B is, in my opinion, right up there with Half - Life 2 as one of the best gmes of the year. Of course this positive reaction is only because I encountered only one CTD while I played, which was my only bug. A word of warning, however, only buy this game if you can afford to spend most of the next week playing it, the fifty hours I played severly limited the amount of The Origin of Species I could read for school.
EDIT: purposefully misspelled "games" and added spaces to "Half-Life 2", how I loath in-post ads.
