Reiner Prokein's long-running freeware library of pre-rendered isometric sprites (humans, monsters, animals, buildings, vehicles, environment), plus 3D meshes, textures and sound effects on the same site. Character zips hold per-direction, per-action BMP frames. The licence is the author's own page: free in commercial games, with a credits line required in the commercial case, and no re-hosting of the raw files.
Credit: required when the game is commercial, as "Reiner "Tiles" Prokein" in the credits
Forbidden: uploading the raw or modified graphics to your own page or a resource site, selling them, or anything that "directly competes" with the site
Buildings page labels the sprites "Isoformat 4:3"; character frames are BMP, one file per direction and action (e.g. stopped ne.bmp), some sets in 32 directions
The home page is now mostly Bforartists news; the graphics live under /graphics/
