Hello all!

I'm planning on running a D&D Game at next years Matsuricon.

Seeing as next year is Medieval Fantasy themed, I wanted to build a game around characters who clearly have a medieval or fantasy bent (Kirito from Sword Art Online, Inuyasha, etc).

Though my main concern is what system to use to utilize it, seeing as they would just be running through a one-shot adventure. I want a lot of character options in case I have more than the desired amount of players at the table (or at least to give them broad options of playable characters should there be, 4 - 6 players).

I was thinking of using Mutants & Masterminds to supplement strange powers, but I also thought of ripping from d20 Modern or BESM to help build characters.

What do you guys think? What characters could be built (at roughly a 5th level standard) and what would you give them in terms of powers and the like?
