actually I wasn't thinking collectathon as much as side-bosses that aren't needed to finish the game but are there for hardcore players to add difficulty... ruby/emerald weapon in FFVII Ozma in 9 etc. FF does this a lot but other games have also added challenge to games this way. I think its a much better idea than having more Battletoads level difficulty games...damn flying bike things hitting walls and crap. or how about ghosts and goblins...1-2 health at the most and then you die.
