#23 - Super Mario Bros. 3

My favorite NES game. A masterpiece of level design, Super Mario Bros. 3 expanded the Mario forumla with fun new ideas like a world map, optional battles, airship levels and hidden secrets. This game also features fun new power ups like the Super Leaf which gives you a raccoon tail which in turn allows you to fly (none of this makes sense but just go with it).

#26 - The second adventure of this stingy billionaire

#25 - The 5th game in this funky series

#24 - Slide and shoot

#23 - Get your stuff back from yourself

#22 - Walker between the worlds

#21 - What lies ahead, only you can see

I'll go with Tekken 6

Tekken Tag Tournament

Excellent choice my friend (It made my list as well).

And nothing else.

#26. Duck Tales 2

#25. Donkey Kong Country: Tropical Freeze because I choose to believe you are refering to Funky Kong.

#24. Mega Man 3

#23. ZombiU

#22. A Link Between Worlds

My guesses... can't think of anything for #21 I'm afraid, and I'm not really sure about some of them .

#23, 25 and 26 are absolutely right. Well done

Game #19 Hint: Shadow Moses
