GD3E is a good system -- but there are a few major flaws within the rules.

Game mechanics are fine until they deal with Hit Points, Health, and Damage management. These issues are too complicated for the type of system that it pretends to be. If you can rework the health and damage, as I have, then it gets another extra star in the rating.

Also, GD3E is based on Active Exploits, a diceless variation of this system. My question is: why two systems for the same game? and why not in the same book as well, or more specifically, why not one book for one system? Why does the one book that explains this concept cost about $8, where as the diceless edition is free?

Another pet peeve I have is when I have to write my own skill and feat lists, when a game does not include these lists within its text. GD3E does not have an easy list of skills and feats (as such), so you will have to write these things down, in order to review what skills are available at character creation. It seems like an unnecessary, yet vital chore for me to perform. Make the lists, fer' cryin' out loud!

I have been reading different "universal" rules systems for the last month and trying to find one that would work best for me. I started roleplaying with D&D 1E basic/expert set and have played many of them through the years. I have been happy with GURPS for a long time able to adapt it to what I want. But it is a bit rules heavy for new people starting out. Even if you use the lite version.

I have played a bit of Savage Worlds as that was recommended to me, but it isn't flexible enough for me. I could hack it a bit to give it a bit more realism and other klugdes, but it would start to become unbalanced quickly in my opinion. Don't get me wrong if you are just looking for a fun system that is easy to pick up and play but not very realistic, SW is worth checking out.

I find genreDiversion 3E to be a really slick system! Reading the rules, I could quickly see how great it is. It doesn't have everything and the kitchen sink included in the rules, although there is a lot, it doesn't need to. It is very easy to build off of the rules and have them work. For instance, I like having an option for someone to start bleeding after a wound, or to use cards for initiative like Savage Worlds. No problem. If I want to make the setting more cinematic or realistic, again very easy to change.

It also has some great scalling rules for changing the power of a campaign or mixing them. You could use the scaling to simply figure out what damage a huge spacecraft's laser does to a truck, for instance.

There are a few fiddly bits that I don't really care for, but I can remove or modify them easily without unbalancing the system.

If you like the EABA system, you will probably like this one. They have a lot of simularities, but I think genreDiversion 3E is a bit better in the design.
