I thought Fusion released way later than 2002, but your post made me look it up.

That is correct!

16 and 12 are correct!

All 3 are correct, although the others beat you to the answers.

13 is Pokemon X/Y.

#16 The Legend of Zelda: A Link Between Worlds / 3DS

After Minish Cap and Wind Waker, none of the Zelda games that followed grabbed me or captivated me as much, until this game came out, I finished it and 100% it in like 3 days, just because I was so addicted, it was a tight and magical game, from its soundtrack and little touches, like intensifying the overworld theme after getting the Master Sword, the dungeons, the item rental system, the upgrades, searching for the cute Maimais, the story (freaking Ravio) the game hit the right notes with me every time, an excellent Zelda game and one of the best 3DS games out there, absolute must play.

#15 Super Mario World 2: Yoshi's Island / SNES - GBA

Is Yoshi’s Island, the fantastic level design, the art style, the great mechanics, the absolute perfect soundtrack, it doesn’t have that many tracks, but the ones it has are nothing short of perfection, culminating in one of the best final bosses of all time, it earned its title of one of the best 2D platformers ever made, if not the best.

As guessed by Farsala, my game #18 is The Legend of Zelda Majoras Mask.

Majoras Mask is a lot darker than the other Zelda titles. Which in itself makes it interesting. And although the basic gameplay is the same, because of you reliving the same three days, timing your actions and gathering masks makes it feel quite different.

As I never owned a N64 I played that game on the 3DS in the remake. Possibly this enhances the experience a bit, I wouldn't know. But it was just a great game. The masks add gameplay depth. In a way they are like items: you need the right mask for some puzzles. But it feels different, especially as you start out fused into one role.

Also, please do not forget that this game introduced Tingle.

Where would the Zelda-series be without him.
