Yeah, they did other things as well, but the Smash games are usually so huge, there's such a ridiculous amount of stuff- scenarios, weapons, unlockables and whatsnot, testing everything till all elements are well balanced altogether - into them, that I have an idea that working on them is a total energy-draining nightmare, and that once you finish Melee or Brawl - that supposedly takes you ages - you are totally fed up with it, yet they prompt you to start working straight away on the next Smash game for the upcoming new console, so they have all my sympathy.
It's like, say, you work in an office and you always end up doing something extremely dull nobody else wants to do such as making photocopies or dispatching mail, you may feel underused since you feel like trying different things, somethink more engaging.
No problem, mate, arguing is the point of a forum and what makes it fun, and unless you don't troll me - and I don't think this is the case - everything's fine, as far as I'm concerned.
