Agree on the simplistic controls.
I wouldn't mind anything from Pac Man to Donkey Kong (arcade classic) to Tetris to Frogger to Galaga. I have to admit, I've never heard of The Great Giana Sisters. I might have played it before without knowing the name of it, though.
Man giana sisters is a classic. Looks like Mario. If you search it on internet you find it easily. I am curious if you played it. But indeed it must be a simple game with simple controls.. https://classicreload.com/giana-sisters.html
Just looked it up...and, you're right, it looks a lot like Mario. I never played it, but I'd definitely give it a go because I LOVED Mario as a kid and still enjoy playing it to this day.
Ok let me know.. There are so much classic games nowadays you can just play in your browser. what was you most favorite one?
My favorite would have to be Super Mario 3, Mario World in a close second.
I bought Super Mario All-Stars for Super Nintendo, around the time that it came out, and probably got somewhere around 1,000 hours of play out of it!
