I don't care about sequels, I for one LIKE sequels, what I *DON'T* like is when the sequel is too different from the previous installments it would have made more sense to make a new character/story instead. I also don't mind the spin offs, cuz I don't play them.
I hated Mario Kart at first simply because it tainted my perception of Mario games, it took the seriousness and danger out of them and tamed them too much for my tastes. But it was a fun as hell and game thanks to my enjoyment of the Super Mario Bros. Super Show, I forgave them. But I have harder time with Golf, Baseball, Soccer, Tennis, cuz I don't care for those sports to begin with.
But what happened to all the Chibi Robo love? That was a new franchise that could mnake for a decent Wii game, lackluster sales be damned it would appeal to the hardcore and the casuals if done right.
