Tycho of Penny Arcade is beginning to post his first impressions of Halo 2, starting with the matchmaking system, which he seems to like fairly well:

It's odd when you first start, especially if you're used to PC-style server browsers or classic Live optimatches, both of which make up for their deficiencies somewhat by being highly explicit. Once you get the hang of this new way, it's startlingly humane and organic in comparison.

And, of course, today's Penny Arcade comic is also Halo 2-themed.
