I liked BioShock, although after playing through System Shock 2 it's obvious how much Ken Levine just copied over.
It's funny because I always figured Infinite wasn't actually received that well, yet on /v/ it always gets the most attention, followed by the occasional BS1 thread, and then absolutely nothing on BS2.
Is Burial At Sea as bad as everybody says? I like the idea of going back to Rapture but I've heard it retcons a lot of the lore.
