Quick and Dirty Dungeons (QADD), an excellent rules lite game that looked like a nice combination of Tunnels & Trolls and Dungeons & Dragons - though note that comes from somebody who is only slightly acquainted with T&T.
The game is 79 pages long and covers character creation, equipment, play rules, magic, monsters, along with including two adventures - one solo and one designed for play with a Game Master - and appendices A through Z consisting of all sorts of useful tables.
The layout of the game is clean and easy to read, and the art is old school black and white ... just like I like it. The writing has a fun style and is clear and easy to understand. The game presents humans, elves, dwarves and halfkins, and warriors, wizards, clerics, rangers, druids and rogues - plenty of options for players.
I think QADD is an excellent choice for pick-up games or full campaigns where you want to spend more time playing than consulting rules. I think it would also lend itself to novices learning how to play rpg's, again due to the rules lite nature of the game and the fact that the classes have simple, straight forward special abilities - not much that requires explanation or memorization.
If you're looking for a game that gets things done, I wholeheartedly recommend QADD. Click HERE to check it out.
