I think puzzles could be used as a really nice way of representing research in an MMO: puzzle solutions represent knowledge, so solving a puzzle would improve things like manufacturing methods.
Players could work together on the trickier puzzles. I can imagine libraries filled with books of solutions, some of them years old, and players reading the old puzzles and working on new ones. Then a group of enemy troops bursts into the library and torches the place down, and all the knowledge is lost with it. Alternatively they could steal the solutions and use them for themselves.
That sounds pretty cool to me.
