My post was in general making the point that i would infact have more fun doing more things. rather than one thing all the time, regardless of how good it is, it's still repetetive. repeating = tedious = tedious = boring does not = fun. so yes, more content, more systems, more fun.
Just because they focus their efforts on few things that does not mean it has to be repetitive. It means they can focus on creating more and varied gameplay systems for said features and fleshing them out, so that there will be more than one way of doing them. Instead of having one repetitive system X, one repetitive system Y, Z, C that are separated from each other. Fleshing out one system well is not inferior to making lots of barebone systems.

atm in the game's current state, yeah, more is definetely better.
Not everything that you could consider "more" equal automatically "better". It has to make sense too. If there are no monsters, why implement a combat mechanic? If there is nothing to craft, why implement crafting mechanics? Those are a waste of time and won't make the game "better".
