(three months later...)

If you can read Japanese, there're at least three house rules for playing RPG in MGE world.
 * 1) The first using GURPS rules.
 * 2) Second, using Call of Cthulhu rules (of all thing). This one is hosted on Kurobinega itself.
 * 3) Third using Sword World 2.0 rules. Notable, while the previous two also design to be erotic RPG, this is only one that turn sex into full combat similar to "battle fuck" RPG games. It's also one that has big change from official setting, old era monsters are still around and remain threat to both humans and mamono alike (Kenkou does approve it).
