This forum (and Google) is filled with posts from people who are having crashes after playing the game for half an hour or so. You DID read the "readme.txt" from the game, right?
From the readme.txt:
"Intermittent Crashes"
"The game may freeze or crash to a blank screen if you play
in one level for extended periods of time. This was typically
seen when playing the game between thirty and forty minutes
without transitioning to a new level or movie. We recommend
that you save the game often to avoid losing progress if you
encounter this issue."
I'm in my forties and have played literally hundreds of games in my life. I'm well aware that people aren't perfect, so anything made by people may not be perfect. This is not the case here. Everyone who purchased the PC version of Star Wars Knights of the Old Republic II: The Sith Lords was sold a game by people who absolutely knew that the game was unplayable and STILL sold it to us anyway. I honestly couldn't believe what I was reading. Because the game was now installed, I figured I'd give it a try in hopes that my system wouldn't have any problems. No such luck. Endless crashes. I'd played Knights of the Old Republic and only had to enable vsync to ensure a perfect playing experience. I've owned every Bioware game produced and they all reek of quality. There were three patches released for Knights of the Old Republic to address problems in the game, none of which was to remedy a game that was expected to crash when it it was shipped. And I don't buy any of the "blame-it-on-the-publisher-'cause-they-made-the-developer-ship-the-game-like-that" bullcrap that is often bandied about. Bioware didn't ship the PC version until months after the XBox release of the first game. Certainly anyone with more than a passing knowledge of that game didn't expect anything different from a new developer on the sequel. I would have waited a couple of more months.
Let's face it, most people don't seek out the readme.txt on the install CD/DVD prior to installing the game to see what it has to say. We read it after the game is installed, either on our own, or when the game inevitably asks: "do you want to read the readme.txt". I have never, and I mean NEVER had an instance when a game told me outright that (and I'm paraphrasing here), "If you play a level for more than thirty to forty-five minutes for whatever reason, (be it because you enjoy taking your time, or you find the game difficult or because you want to explore every nook and cranny), without your playing time leading to a cut-scene or level change... the game may crash. So save often to avoid our mistake from causing you to loose your progress, in addition to your patience."
This is beyond inexcusable. I brought the game, and the strategy guide back to the EB where I'd purchased it and politely described why I wanted my money back. Within five minutes the manager had reinbursed my $69.98 ($49.99 + $24.99 minus game+guide discount). No more Obsidian developed games for me. I own an XBox, but won't buy the game in that form either.
