My friends are I enjoyed Terraria alot more than the starbound beta solely because we had to keep re-trying bosses in terraria, and coming up with strategies...I would really enjoy more challenging boss battles rather than content. Starbound has such a great weapon generation system, yet any weapon you get will suffice for any boss battle...There is no point in finding a good weapon since the game is so incredibly easy. These are my thoughts
Hopefully the game will get more difficult and enemies will get harder to fight as they balance everything.
