I must say, one particular ending seems to yield a significantly better result than the others.
Indeed.
I replayed the game from the end of chapter 1 and I´d say the
route has overall a bit more fleshed out content.
Dandelion and Zoltan are a bit more involved, environments a bit more varied, more main story/character aspects are revealed, there´s also more choices, side quests (including one pretty good "treasure hunting" one), slightly better itemization and generally a bit more gameplay variety.
Playing this route I´ve finished the game with level 37 worth of experience (level 35 is cap) whereas similarly quite completionist play through the other one yielded only level 33.
Besides some general complaints I´ve already mentioned in this thread, my only two complaints specific to this route would be that one of the monster contract quests is rather badly explained and the LotR references (not one, but at least three!) would be better cut out as they all feel very out of place.
Anyway, even though I think this iteration of ch2 + ch3 provides overall somewhat more fulfilling experience, that definitely doesn´t mean the other one lost its merit - it is significantly different story/character-wise, its version of chapter 2 has more unique feel and, well,
is awesome and remains my favourite character in the game.
