   I remember first seeing such a proof-of-work in the network protocol layer of the game Tribes 2. They opened up the source code for that, named OpenTNL (seems abandoned now) where you could see how it's done. Here's the part that

    You might give KeeperFX a try. It's a mod that reuses the existing exe file but builds around it. IIRC it allows higher resolutions, adds more maps/campaigns and makes it possible to run Dungeon Keeper on newer Windows versions wi
