For laughs/nostalgia from this post I decided to Google the editor, figuring that it would have been mostly lost to history.
NOPE! I was very wrong. There was a new release today.
The community around these games is really amazing.
I still play Blood mods everyday. If you like the game I would recommend the Eviction mod.
Its a sad state of affairs. There are moderns games with vibrant modding communities (Factorio, Rimworld, Minecraft, Starsector, Battletech, Bethesda games, to name a few) so clearly the demand and the skill is there, and things like the <Game> Nexus and Steam Workshop help discovery and distribution but so many games ship totally locked down with no real avenue for the community to expand or add on to them. Its very disappointing.
