I don't like MMOs either, but I really like the first PSO. I don't know about #2, but the first game was hardly an MMO...you just had a lobby, and then you'd form a party of four (max) and have your own private game.
We mostly played the console versions offline, though. The versions after 2.0 have split-screen.
