Oh, I actually forgot about the Jak trilogy. Have you gone back to that at all, recently? (See, it's starting already. I work fast! ) I finished Jak 2, but am on the fence as to whether I want to try and get some of the other trophies for the precursor orbs and whatnot.
I did it all in one go as well. It helps that way because you're able to flow through the game without the risk of losing track of what you've done (something which I've definitely managed with my Monkey Island 2 save)
I think my speed run took 2 hours and 40-odd minutes, so a little closer than yours. Now you've done that, I'll have to go and find a new reason to pester you.
