Dungeons and Dolls is a dungeon crawler with a more casual style, one of those games that lends itself to sessions that can be as short as half an hour or as long as an afternoon(or longer if you get really obsessed, lol).
The basic gameplay should be familiar to anyone who has played any of the old first person dungeon crawlers- you go around a 3d dungeon, fight monsters and take their stuff, then use your loot and experience to go deeper into the dungeon and fight more monsters so you can get more experience and more stuff, enabling you to go yet deeper and so on.
