You stole mine!
Buck Rogers had a fairly crazy character system with a Hell of a lot of Depth. Skills were divided in to categories, and each class got bonuses to certain skills.

Not all these skills were used in the game, because SSI liked to add every part of the character system to their games since characters going from one game to the next were a staple of their Gold Box games. However, you can see that the Buck Rogers tabletop(which was made by TSR) system influenced later Dungeons & Dragons skills. You'll also notice that since there isn't a magic system, some spells and other class abilities from AD&D worked their way in to the skills system. It is kind of amazing how many of these skills were used in the game. I believe one that isn't useful is Drive Groundcar because the first game didn't have any cars.
