The curiosity system is clever and all, but really, now it's 10 times as hard to gain any LP at all. It's incredibly easy at the start, just look at everything and pick up everything and you can rack up a sum of about 1.5k LP, yes, but then you have to rely completely on curiosities!
Back with the old system you got AWARDED for progress! You could get a good thousand LP from plowing, planting and harvesting a field of wheat (and a lot of times more than that if the field was big enough). With the current system, you're working for nothing. You don't feel the same joy anymore, because now a heap of wheat is just a heap of wheat. It's not a goldmine of LP anymore.
Really, bring back the old LP system! The curiosity system is nice, but it's not good enough! There's no award in doing anything anymore!
(Alternatively cross both system and use BOTH curiosity and the old LP system).
Pretty please, Jorb?
