I'm wondering if anyone else on these forums plays Dungeon Crawl. For those of you who don't know what Dungeon Crawl I'll tell you. Dungeon Crawl is F2P, open source roguelike. Gameplay involves exploring a massive hand built dungeon, killing monsters and leveling up. All in all it's a fun little game. Download it Here and read about it here or here. Have fun crawling!
You can also run it on any computer that's not a rock.
