Before Gunparade March became an anime series it was a cult hit PsOne game developed by Alfa System. Sony published the experimental title, which was kind of like a school simulator.
Gunparade March gives players a decent amount of freedom for a PsOne game – you can study, go on dates, start fights with your classmates or focus on becoming a pilot. The school sim is part, probably the most interesting part, of Gunparde March. There are also Evangelion-like monsters to defeat with a tactics-lite system.
If you missed it and have money loaded in a Japanese PlayStation Network account, you can download Gunparade March from the PlayStation Store. Sony is selling a digital copy for 600 yen ($7).
