I like Zelda, but I'm not the biggest fan. OOT was alright, but not the best thing ever, I love Majora though. Haven't beaten any others so can't really comment on them but I tend to get board with Zelda 1 after the first dungeon, same with 2.
I have not gotten into much of Mega Man, namely MMX.
Also SEGA, in general. I have a Dreamcast and Genesis, and there aren't many games I want. Ecco is boring and kinda crappy, Revenge of Shinobi is boring, Golden Axe if fun, but gets boring after a while,
I like sonic, but most of the games are Meh, Excluding 2,3,Knuckles,Rush
Sonic Adventure is mostly meh, same with 2, The Sonic stages are fun, not the best, but fun. Tails stages in SA1 is Sonic, but with a annoying character and a easy way to cheat (flying). Knuckles/ Rouge stages are crap, it is Banjo Kazzoie with all the fun removes. E102/Tails SA2/ Eggman stages are fun but very easy. Amy is meh. Big is completely out of place.
Super Mario Bros. 3. I loose interest in World 2. It is just not as fun as SMB 1 or SMW. My biggest complaisant is the levels are too short, there are a lot of them, but the flow is broken with the almost pointless map screen.
To help prove my point, compare the first level of each game:
