Actually, "Google" isn't a word, even a mathematical one. You're thinking of "googol," which is 10^100. Supposedly the founders of "Google" meant to use "googol," but misspelled it. That doesn't say much for their spelling skills.
This is relatively common knowledge from Steve Jackson's Stakeholders' Report. Due to Munchkin's current popularity, keeping their retailers and customers supplied with Munchkin sets and expansions is their top priority. That's not to say that GURPS will be ignored, however, but demand is higher...

I have no suggestions for a prelude, but Red Hand of Doom begins at 5th-level, despite what it says on the cover (and goes until 10th). The interior of the adventure assumes a level 5 to 10 adventure, not the 6 to 12 on the cover.
