Last weekend I got to DM a game using my own races and classes in a science fiction-setting, where people flew through fissures in space on giant space whales called Starbacks. I helped the players build their own characters from 6 races and 12 classes and then we got to it! And things went pretty well! It's largly shooter bassed and we had a lot of fun, using what's basically a heavily moded 4e model which we were all familiar with. The races are Paladon, Vizigoth (Vora "Red", Yuri "Purple"), Mow, Lageckian, human and Tion.
The classes were:
Commando, Assassin, Outlaw, and Technomancer (Strikers)
Desperado, Champion, and Augmenter (Defenders)
Specialist, Enfrocer (Controlers)
Bastion, Vanguard, and Bodyguard (Leaders)
and each drew their power from either Technology, Military, or Adventure.
So far I've made choosable cards for the 1st level of each class, a race card for each race, and features, plus a multi-page store of weapons and armor which the players got to buy from with a 1000 iu (interstellar unit) starting balance, and a general dictionary. Our first game was pretty much a playtest, but there's a lot more information that I hope to add to this thread!
