Loved playing with GunZ as a kid. Learning J-Style, K-Style, etc. The multiplayer offered both PvP and PvE action. Licensing of the game was so inconsistent though, it went from MAIET to Ijji to idk lol, and of course you can't forget about the awesome private server community. In terms of an actual story, however, it was a total mess. The simplistic execution that drew in skillers from all over the world (and the fact you often found yourself in their presence) was the charm itself.
