Maybe not always. But Half Life 2 was born and raised for PC, like it or not. Besides, it's wonderfully optimized for PCs...you don't even need a good PC to run these games.
Valve is one of the best developers for scaling their games to work on crappy and gamer PCs.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
