Well it is clear that indeed dragon origins age is THE RPG that stands out, a pleasure for Bladur's gate 2, although the latter, in my opinion, is not equaled.
DAO is a good gameplay, stunning cinematic, a scenario that takes the road and above all the companions with individual personalities, different stories and that can lead you to their own search. Romances are possible even, that embodied a male or female character !!
In this game, you have to make decisions that greatly influence the course of history, so think carefully before you answer !!
At the difficulty ... well even in normal level must be a good strategist, yeah, we're not in diablo, the word "all forward, nag warrior" it does not work!
At the duration of the game, I will say about 80h.
Two slight defects are nevertheless worth noting: download times between areas, and also the bad guys ... They're good bad guys ... Monsters what ... And without further unfortunately.
Note that it's a very bloody game, so do not put it in the hands of young people.
In short: for me it is the best RPG since the saga of Baldur.
