Hi guys. I'm the developer of the game Virtual Pet Collector. I'm actually a really HUGE fan of DCSS, It's one of my two favorite games along with Dwarf Fortress.
I got the most of my early tiles from
http://rltiles.sourceforge.net/ which claims they are in the public domain. I've replaced many of them with purchased artwork since the beginning but there are still many RLTiles in place. I don't really make any money from my game so it's taking a while to purchase better artwork for it.
I've also used the tiles in another game I made for 7DRL.
http://www.timothysmurphy.com/games/Ari ... index.htmlI believe I found out about them from RogueBasin.
http://roguebasin.roguelikedevelopment. ... ical_tilesI was under the impression these tiles were in the public domain to encourage new game development and make it easier for programmers to quickly get stuff out there. Am I wrong?
