I never ate possum. But I understand that the (abundant) fat is sweet and not gamy like raccoon. To taste like bacon it would have to be cured like bacon but it wouldn't surprise me at all if it tasted very much like the pork belly or jowls from which bacon is made.
I have eaten armadillo on several occasions and it also resembles pork and has no gamy taste.

Good coffee, good weed, and time on my hands...
