Were there things that you wished you had added to either Fallouts?

Yeah, lots. Fallout 1 should have been about 50% larger, with a better endgame. I mostly wish about the things we could have changed and tweaked in the SPECIAL system. We didn't spend a lot of time on the system once we changed over from GURPS. Tim, Jess and myself cranked through the system pretty quickly (I remember one very intense week of scribbling on the whiteboard in Tim's office) and then we spent most of our time finishing up areas and getting the game done. I wish we had refined and cleaned up the system to remove things like non-useful skills, fixed the time puzzles/invasion events and fixed the combat system so it wasn't so Fragile Ninja-ish. I also wish we had done the game as a set of editors, NWN-style, but that would have been a much different project.
