O man!!!
I didn't play those games you listed here but your post just reminds me of those years I played Sega game. I didn't have it at home, so I'll always go to a friend's place to watch and play.
I didn't play much of the Role Playing Game (RPG) on Sega actually. Sonic was my favourite and then Soccer as well.
I began playing Role Playing Games on Mobile with less Action Games like The Sims and New York Life. I don't know if they actually fall into the modern classification of RPG.
But great post by the way !PIZZA
Its was a good childhood with simple games , i also played sonic i remember that its taked me about 6 hours to beat the boss and Finnish the game .
Hahahaha
Different levels and different bosses.. it just reminds me of another game... Contra, did you play it?
