We've only had Internet multiplayer in for about a month and a half.
What ?!?! ... So when I was hosting games in December and November, with some users joining my games by the Internet, I was hallucinating ?!
I'm 58¾-years old : my memory must be playing tricks on me. (But I'll recognize that my "5¾ months" figure was inflated.)
What I meant is this : I've been in the beta for 5¾ months, and unless I host, I'm still stuck into playing alone against the A.I.
Learning that you guys had a swell stress-test with a lot of MP games going on does not cheer the significant minority of us ordinary Joe users who experience a lot of trouble with joining games.
This being said, I'm not really complaining : I like to play against the A.I., and I suck at MP against humans, so it's not a great loss for me. I'll remain very happy with my game purchase, even if I never, ever succeed in joining an Internet game.
But others might not be as "philosophical" as I'm content to be ...
