I've got the originals via emulation, so getting hold of the games isn't a problem.

Did you know that it is still possible to play Phantasy Star Online v2 on the PC and Dreamcast? Some people developed a custom server that could be run on their own, so people could continue playing the game without the original Sega servers still being up. I did log in and play a couple of times on the custom servers a couple of years ago, but they only ever had 3 or 4 people logged in, so it wasn't very good.

Very different to the days on the Dreamcast when you logged into the game and there were hundreds of people on the mothership walking around and chatting. That was great. And it was free to play the game online in Europe too! Not like US and Japanese players, who had to buy a "hunting license" to play online.

You really should try one of the more recent versions of Phantasy Star Online to see what you think of them. However if you prefer turn based combat to real time then you might not like it as much, because the combat can be quite hack and slash, but with lock-on targetting and some tactics involved, plus the ability to bind abilities, moves and weapons to key combinations. And the level design and story is pretty good too.
