I’ve never bought this excuse, because they have absolutely no problem having ideas to justifying sequels…..as long as they sell a bajillion copies…..like Kart. No problem there.I mean, hasn't this been said to death? They simply haven't had an idea that justifies a sequel. That is the mindset at Nintendo for most of their games and I don't necessarily disagree with them.
It's a little silly in case of F Zero though, since just having a new game with modern graphics would be enough for most people.
This is nothing but their excuse to enable laziness because the RoI isn’t there enough to have them want to bother with the innovations that are at the core of their design philosophies.
