Super Smash Bros. is #1 because it is a celebration Nintendo history and also a celebration of the most influential video game icons starting with the latest entries in the franchise. It is the epitome of fanservice. Even if fighting games aren't your thing, it's hard not to appreciate how much love and care goes into representing these characters and their worlds to the best of their abilities.
The other four are just franchises I love and spent the most time playing and investing in. I can't really add more than five without singling out specific games instead of entire franchises.

2. The Legend of Zelda
3. Metroid
