I don't think I agree with the "For Everyone" rating of The Legend of Zelda: Majora's Mask. The game has several poorly designed restrictions which make it extremely difficult to get into. Only fans of Zelda have a chance of liking it.
It's also a stretch to say Kirby Super Star has nine completely different games when five of them are platformers with slightly different goals.
See, I knew someone was going to say that Majora's Mask is not for everyone because of the time restraint. When I was writing this, I kept going back and forth between recommendations. I do believe that the time restraint is enough of an issue for some that it warrants a "Recommended for Fans" label. However, at times I feel the time issues are overblown. Too much is put on that aspect on the game and not enough on everything else. At times Majora's Mask surpasses Ocarina of Time. The character development, the world, the dungeons, the magical masks, a lot of things make Termina one of the most fascinating game worlds I've ever experience.
And that's why I recommended the game, because it really is that good, and should be experienced at least ONCE, even if you don't like it afterwards. We often complain that games don't take enough risks, and Majora's Mask does a good job of it.
Regarding Kirby, yeah, the games might be running on the same engine, but the concepts are very different. The Great Cave Offensive is an exploring game with emphasis on collecting items, and the gameplay is much slower. Spring Breeze is a remake of the first Game Boy game. Milky Way Wishes doesn't even have Kirby's sucking ability, relying on a different method of obtaining power ups.
These are small changes that completely change how Kirby is played, hence why the game is varied despite using the same engine.
