Shadowrun is probably my favorite system. I'm actually trying to run a game of it (my first time as gm) if I can get my players all available at the same time, that is, hehe.
The core book is intimidating, but a lot of it is story flavor.
Welcome! It's great to have you here. Your work sounds very interesting. I'm sure there's drudgery in it, like in every job, but overall, it seems pretty great.
