Quite probably everyone of you has played a video game with some sort of grid based inventory system. Deus Ex, Stalker and Diablo are prime examples. How about we try this for a pencil and paper RPG?
This would get around the usual problems with encumbrance rules - poo visualization of how big/unwieldy something is and lack of knowledge about actual weights or sizes. Equipment markers could also have an image and game stats on them to assist recognition and game flow.
