Doodle Dice Monster is an unusual name for a system. No mention of dragons or dungeons. No mention of space ships, far away planets or even of guns. Don't let that fool you, doodle dice monsters bring out your creative side and a whole load of fun besides!
Using your selection of dice and your ability to draw you create monsters of crazy proportions. Then you assign dice to their attributes then you duke it out. The creatures can be pretty much whatever you desire them to be. There is rules as to how to how you create your monsters (as they describe it in the book, the monster could have hundreds of limbs and eyes but these don't do anything unless you assign to them).
There is a clear set of rules as to how combat goes on. They are sensible and easy to follow and it explains how the win/lose conditions can happen. Even the colour of your die that you use can make a difference in your combat actions (and explains what to do if you have multicoloured die).
A clear glossary for any confusing terminology used throughout the rules is available as well as a list of awesome alternative rules to throw into your games as well (how about using an avatar of yourself to help you win?).
This is great fun, and a joy to play. The game is easily accessible to anyone and is a great introduction to anyone to get a feeling of roleplaying is like. I can see this being a fun convention game that is easy to pick up, easy to play for anyone and more importantly doesn't have to take an age and a half of time to get going. In my opinion, I would love to see this featured on Tabletop, or even play it more with my friends. Because half the fun is beating each other up with your created monsters and trying to win. The other half is seeing the crazy monsters that escape from the imaginations of your friends, families, random convention goers or even to see the monsters that escape from the mind of Wil Wheaton.
The only thing you could have against it is that you won't be able to make a massively long and engaging storyline, or a campaign that spans months or years. What you can have is something that you can play as filler or something that gives you a break from a serious campaign. It can give you something to help you just have a laugh without the need for hours and hours of prep.
If you want something fun, light and easy to play then this is exactly what you are looking for. I will certainly be playing with my friends for a good barrel of fun when we have a spare hour or two.
