i think a good challenge would be to take a character from an old 3D game that has a really low polygon count and remake it. like how the FF7 characters went from being people with cubes for hands to super detailed people I have heard this idea before and I liked it then and I like it now, but alot of the old games are being remade now so its getting harder to pick some - maybe do the classic twist of a sex change - take an game character and update and change the sex of her/him/it. Even robots could be changed some high teck to old teck/steam punk. But I`m still wanting the next one to be an environment one - but there is nothing stopping that from being an old game set being updated - a little bit like the remake of the monkey island games or resident evil on the game cube (now that was an overhaul).
