One thing I recall hearing about, and don't quote me on this because I've never even looked at the wiki, was galaxy shuriken and mecha large enough to use them. Just on that note alone, I'd say TTGL wouldn't be putting in an appearance - not at anywhere even remotely close to full strength, anyway.

Then again, I'm just a reader. Speaking of which, I should find a copy of one of the Lensman books...

(Then there's that whole 'drill to pierce the heavens' thing. Which I still can't think of as anything but absolutely hilarious.)
