To begin with, I have to say the graphism is good - maybe not the most extraordinary style, but it's well executed. So is the music. The lenght is reasonable, 20 h maybe.
The characters are well made, all of them - not only the three you control. A lot of memorable characters with back stories, the universe feels habited. And there are nice dialogues, enough funny descriptions too make this a nice P&C game.
I'm more sceptic about the puzzles, that are very directive. Sometimes you just have to go and exhaust al conversation topic of character A, then character B then back to A and you're done. And some times you just have to take all the items on the screen, combine them togeter and voila. The puzzle part doesn't ask you to be smart or anything, it's a real weak spot of the game.
Then, the references will please you - or not. A bit of Star Wars, some LOTR, a whole scene stolen fron Fate of Atlantis, another one from Monkey Island (twice), a character from the Diskworld, Oh, Lechuck. Oh, a bit of WOW. the game is FULL of those stuff. I found it funny at the begining, but tedious after a while. Somtimes it's trying to be funny by connivance, sometimse it's just stealing the funny parts of older games. Your mileage might vary, but be aware of that, you will like it or hate it.
All that didn't prevented me from enjoying the game, but it's far from a perfect game - you might shake your head a few time.
