From Chainmail to D&D Next
Big Eyes Small Mouth 2nd Edition, Dungeon
This is a generic anime game, and it has a D&D like fantasy supplement. BESM has a point buy character creation that creates highly diverse characters, which can cause some balance issues. The system is a clean 2D6 + modifier. BESM or OVA and good medium complex rules set for just about any genera. If I wanted to run the D&D carton this is the game I would choose.
Play this game when you need a flexible ruleset with light tactical combat. It allows for diverse characters and role-playing. It is a very enjoyable generic system, with some great supplements.
