...a new Q&A with developers GSC Gameworld mentions that they're contemplating turning the sublime post-apocalyptic shooter into an MMO.
"If you mean an MMOG, then we are seriously considering it", is the exact quote. No more details than that, but it's more gossip than proto-videogames generally yield. Let there be much rejoicing.
Certainly, colour me excited. Stalker's world is a compelling place even in singleplayer - as a living, breathing multiplayer Zone, filled with rival gangs of human-controlled Stalkers vying for survival, artifacts and cash, it could be astonishing.
Or, y'know, horribly broken. Much as I love Stalker, the amount of serious bugs in it has me concerned about just how horribly fractured the inifinitely larger project of an MMO version would be. Plus, passing guys called DeATHmAST3R_5000 would really trash the atmosphere. But still. The trading/killing/surviving infrastructure of the game is well-suited to persistent world play, so I'd love to see this happen. It's either that or Fallout Online as far as I'm concerned, and the ongoing red tape of the latter means World of Stalkercraft already seems more plausible.
