The X-Box version needs patching too. They just can't really do it since there is no Live connection for the game. The headaches are coming from LA's inept handling of the situation.
LA rushed the game out.
LA's QA for the game failed.
LA is now holding the patch for whatever reason.
LA is the one not allowing Obsidian to finish the game.
If peeps at LA weren't being a bunch of incompetent jackarses about the release of the game, rushing it out before completion, and so forth we wouldn't have half the problems we have right now.
Don't blame the PC gamers. Blame the publishers who are acting stupid.
