I’m not sure I agree with this list. From an MMO centric viewpoint, Anarchy Online, and ESPECIALLY World of Warcraft should be on there somewhere (its issues were very similar to Steam/Half Life 2’s). In fact, it took until a few years ago for MMO launches to NOT be automatically assumed to be failtastic.
Fun trivia tidbit: DAOC had an almost flawless launch day. It went down for about 15 minutes on launch day. That was all my fault. Uh, sorry!
