I agree, at the end fo the day, there is not much to these other than conversation starters but still, I can see them being popular with certain fans. Interesting they went with two Sonic games in this set rather than another Sega Genesis title (Golden Axe, maybe?).
I have a lot of collectibles that mean nothing to others but to me, they are the best. From old Go-Bot knock off bubble blowers to a partial Trypticon from the 80s (and a bunch of miniature dinosaurs).
