Ruleset is an improvement over D&D
I can't agree. Working towards prestige classes or multiclass your characters beats Drakensangs system and don't start talking about the magic system.
But...Drakensang is a Party RPG. So if you could stomach NWN2 OC, give it a try.
Plus it features the most sexy pixels in an RPG since Bloodlines.
Towards the last third of the game you can revisit some locations. So it's not 100 % true, that you can't go back.
