So, NCSoft has been working on localizing a game called Exteel. It plays somewhat like a cross between an FPS and Virtua-On. As you fight, you gain credits you can use to purchase new mech parts, weapons, special skills, etc, as well as levels you can spend to give minor increases to your base stats.
I've been playing since the first closed beta, and it's great fun. I encourage everybody to at least give it a shot.
