BEAN! The D2 RPG is a very simple and effective system which works best as an introductory system for young or new role players.
This being said there's no reason why you can't have a lot of fun with this game, especially in one shots or shorter games.
The basic mechanic involves you "rolling beans" which is an Attribute dice pool best represented by coins, marked beans or anything else that has two sides where one side is a success the other is not (although a bunch of D6's with odds and evens would be fine). Success are then compared against a difficulty number.
Skills are in anything you wish and allow you to reduce the difficulty of a task by one. Combat is as simple as comparing positives, certain equipment giving you extra beans to roll and the winner inflicts damage (after any armour) by subtracting the success of their opponent.
There is a good sample of equipment, spells and monsters and whilst there's no in-depth monster creator there really is no need, it's very simple to just file off the names of those already in the bestiary.
Whilst there is a very short solo adventure (think fighting fantasy) and group scenario to get you going there isn't any setting as such - other than it's set in "Bean Land" which is really only an excuse to put in the wonderfully silly and gentle artwork that seems to be excellently placed for its target audience (new or young gamers for the most part). However Bean! is aimed at fantasy more than anything but coming up with a generic game isn't difficult, especially when the rules are so simple.
Obviously not intended for long running gritty games BEAN! is none-the-less a delightfully simple and humourous set of rules that works much better than expected, allowing quick gaming for those days where you really don't want to spend much time on a game but want something fun and enjoyable for your players (young or old).
I would mention finally that the price is excellent, and because of it I end up purchasing the print version which is of excellent quality and great for passing around the gaming table.
