the only thing that lacks in gaias in MY opinion is that some bosses are a bit boring. (Crab, Wolf, Golem, Zibnix, Protector), but i have to say that there are a lot of cool bosses like fl, vamp or ancient one
sry to say that, but what u listed... is crap:
-game isnt too short if you include the dungeons
-there are A LOT of items
-well the skills price is good, otherwise its too easy to obtain them
-weather effect is just cool
