Why? A single player focused PS game, finally.... and it just sounds worrisome more than exciting.
It's Phantasy Star, you don't need to have a planet where existing skill sets won't work. There's nothing wrong with having an alien priest, a guy with a sword, an android with giant cannons, a genetically engineered girl with cat ears, and a wizard all working together.
"But we need to create a realistic world. Why would someone fight with swords when such amazing magic and cyborg-cannons exist?"
Fuck you guys. Some people suplex trains.
Will I buy it? Almost certainly. Will I gripe about it? I have since PSO came out, I'm not going to stop now. Give me back my Algol solar system, damn you.
