I've never played a Phantasy Star game. I'm slightly interested in playing through the first 4, 1 on master system, 2-4 on genesis. I have IV on cartridge, and was going to play that one first, but (here's my actual question) does the order matter, story-wise? Is this series like Final Fantasy, where the stories aren't connected but the 'universe' is cohesive throughout? Thanks, just curious about some old games I never played till now.
