Don't compare to diablo. Diablo's hack 'n' slash, this is *role-play* and for Gods' sake it is a role-play game. Although I like diablo and i've got the expansion as well, well, it's nothing much really, besides good graphics and lots of monsters and a well-organised online network. Divinity may not be 3d, which is best imho, and it may not have the coolest graphics ever, but it's interesting, it does not limit your choices [thousand ways to screw up] and you can very well finish the game with a less than ordinary suit of armour, which is frankly an achievement compared to other role play games out there. How may hours? Take your pick, it's up to you. You can even finish 12 lvl, someone has done that.
