Supercolossal +1 to Heretic and Blood remakes! I still play Blood from time to time in DOSBox. Awesome game. I loved Blake Stone when I was little but feel a modern version could lose the magic of the original. It would need to be "retro" styled I think interms of music, visual design etc.
Blood was an awsome game in terms of the weapons used.
It was and still is in my opinion the most creative weapons in a game up to date.
Not to mention it was the 1st game that added alternative fire mode that actually was fun to use.
