One of the other things I wanted to explore was a classless system to D&D, where you are free to build your character as desired, similar to Elder Scrolls. The RPG my coworkers are making called Gram RPG operates under such a system. I think it might be too much for D&D, though taking Gram and modifying it to be whatever we want is really easy. They have made it quite versatile. It relies on a well-built character, four ability scores, and many status conditions. Otherwise, it is extremely easy.
I plan to read over it a little more and hopefully rework the North Campaign (Sparky Grawler) into a Gram campaign. Character creation is very easy–the hardest part is choosing your abilities and developing a good character background. There are a few other things I don’t understand, and its flow of story is different than D&D, but that’s nothing that couldn’t be remedied.
I will work jointly on my 5e campaign and the North and will let you both know when I get nearer to having at least a one-shot.
