I'm hailing from the ancient times where getting a "game engine license" involved several in-person meetings both between top-level management followed by engineers, followed by exhaustive due diligence from both sides, intense haggling for several months, and finally signing a proper "contract", handing over absurd amounts of money upfront and then paying royalties after release.

That's basically what I understand as "getting a license", OTH I accept probably 5..10 EULAs a week without thinking or even reading the text (most of them are not enforceable anyway).
