For some personal reasons I still prefer DD above DKS, so my first and all time favorite RPG is Divine Divinity ! My second for sure now the DKS ! Still, after all the years I played DD, it remains very addictive ! So addictive that this is the only game in my life I played more than ones till next morning ... when the sunlight wakes me up, out of a loooong Dream that is Rivellon ...
I don't love guns, so all FPS I don't wish to play, even it is a shooter with lots of great RPG elements !
O yes, forgot to mention : Oblivion is also still waiting at me ... but the problem with Oblivion I have is that leveling up system that, after a few "attemps", can't take my attention for long ... I can't say Oblivion is bad, not at all, but not a RPG that suits my personal RPG preferences best, so simple it can be . At some time I try it again, ... ever ... or maybe never ...
On 7th of february 2015 : I start a new adventure in the Divinity world of Original Sin, it's a Fantastic Freaking Fabulous Funny ... it's my All Time Favorite One !
