It was bound to happen that Bioshock was subverted by Halo 3, although I didn't expect it to happen to me, since I promised that I would play through Bioshock before I even picked up Bungie's monster title.
Fortunately, I caved in on the 25th and picked up the Limited Edition and I am playing through the campaign. Regardless of the "not true HD" backlash that I've been reading on the site (and others), Halo 3 is a beautiful game and I am enjoying it immensely. I'm sure I will get my licks in with all the multiplayer modes after that, and make my way through the higher difficulties.
And then I guess I'll get back to Bioshock. Sorry, 2K, but Bungie has you beat for a little while yet.
