That's awesome! Call me crazy, but I had a lot of fun in PSO too. Definitely not the same game. I'm still waiting on a modern Phantasy Star. But, what can you do after IV?
Play Phantasy Star Generations 1 & 2! They are a remake of the classics with beautifully upgraded graphics. Released for the Playstation 2 in Japan only, however I think there is an English translated version by Kyence.
