Why? Are these not aspects of the game?
When you buy BioShock, you're getting all of these things/issues, so why would it be appropriate to factor them out of review, even if they're worth mentioning?
Hypothetical question: if a particular game can run no faster than 12 FPS, would you factor that issue in the total score?
First off, DRM. Has no impact on the actual game itself. Nothing more I will say.
Second. AA. This is an optional feature. It makes the game look better, yes, blah blah. There is no NEED for it in actuality.
Third. WS. You could argue that the lack of proper function would take the game down some points. Fine, I agree. If something is not implemented correctly it should be noted. But WS is not enough to take it down to 8.5 seeing as how the other 2 are already not enough of an issue to bring the score down anymore.
Having a game run at only 12 fps would make it virtually unplayable. So of course that would affect it's "score." Reviewers all the time comment on how a game will only run at 30fps (for console obv), but how much that affects the review is based on the reviewer. Hence the score quotations.
