Dekaron is fun, but...
-very hard to level up, especially after level 100
-very hard to make good money, prices for items are really f***ed up
-complete absence of story, it makes you feel you are going on just to test your skills
-almost no quests to do, and the little quest you have they don't reward you enough
-complete absence of endgame content
-high level mobs are absurdly strong
-no gander selection
-no faction to choose, we are all the same
If you want to play this game, you must have a looooooot of time and be a "lure-the-mobs-and-grind-your-ass-off" type, no jokes: as I said before, quests reward makes you laugh, even in higher lvls.
+very dinamic, skills animation are amazing to watch, and slashing lots of enemies is fun!
+a lot of maps (although they are little) and catchy
+classes are nice and well presented
+very nice inner abilities, like demon transformation and so on (this will be in the next patches though)
Recommended to: hardcore gamers, with lots of time free, who only care about action and not story/walkthroughs
