That's because it's made by EA who operate on Origin, which is enough incentive to not even bother. I have it, but most times I decide I want to play it Origin wants an update, by which point I've lost interest.
Asassins Creed III is good on PC, can't seem to alter the graphics for it though. Maybe I can't find them menu or something. I'd get it if I were you
Also get Half Life 2, the graphics aren't super amazing but it is such a great game
Edit: Oh and for the love of God don't download BF3 from Origin. Get a disk!
