DA 1 is like... Baldur's Gate 2 light. It's that, not bad, but surely not more.
And yes, I would not recommend it. Sometimes, awesome games simply have lived out their time.
I still consider Planescape: Torment the best game ever made - but I really would not "recommend" it anymore.
Diablo always has been Hack & Slay, so I'd not draw this into a complaint on how they do not make good RPGs anymore. It's a bit like using one of the old VW Bettles as example in an argument they do not make "those sturdy trucks" anymore. It always has been from a different genre.
Two Worlds was one of the most disappointing games in the last time. It has nothing of the "great games of old" (as Divinity 2, for example). I have no idea how that fits in the progression "Divine Divinity/Baldur's Gate/Divinity 2".
