I drew my version of the six characters of the board game Cluedo and made with them these playing figures to be used instead in the ordinary colored pawns.

I printed, cutted and plastified them and used lego pieces to make the bases.
I also designed the murdered guy... but I didn't made a figure. Maybe I'll use it for a new solution's envelope.
The next step should be making the playing cards.
I'm also thinking in customize the game to be used with Lego minifigs, using any kind of characters and weapons (lego weapons, of course: bow, katana, axe, light saber, blaster, club, spear, rapier,... stereo,... ). All the cards should be re-done with good photographs... but it should be very funny. 
I love boardgames and have done some custom ones myself, so I would like to see more.
