My favorites were Ninja Turtles, Final Fantasy, Paperboy, Zelda, Rygar, Castlevania 3, or Kid Icarus. At least those ones got massive amounts of play time.
Kid Icarus is a little too difficult for me, but I think I should try again and see if I can get better.
I only played TMNT on SNES, perhaps I should try the NES one.
I never tried Paperboy, is it good?
I never said I was good at them. LOL. I enjoyed them all. For the time they came out, they were amazing to me.
I think the part I liked about TMNT was that it had multiple play styles in one game, so it felt like more.
Paperboy was a racing game with a timing mechanism. You ride a bike along a set course, dodging obstacles like the racing games of the time. However, you have to time throwing papers at or in mailboxes to get points to pass stages.
