With all due respect to Felix, if you would not mind i'd like to post my own recommendations
Your being new to the genre (and as such likely accustomed to a different graphical fidelity standard) limits my list by a very lot sadly, but perhaps after having played these you will come to see how image is not King after all. Should you get there, or if you you think you are already, i'd be happy to pinpoint a whole load more. Most of the treasures of this genre are from a now..more or less bygone era. So for starters then:
Planescape Torment (story done right)
Jagged Alliance 2 (thinking/combat done right)
- note here being that if googleing Fallout I and II doesn't make you cringe, you really should give both a try first. Not Tactics, not the even later Bethesda abomination -
Wizardry 8 (first person done right) ((and hopefully your first blobber))
This falls outside "the starters" list, wouldn't wish to scare you away! But i can't help not listing it..so if you think you could give it a try nonetheless?
Ultima 7 (interactivity done right)
(D:OS is basically a love letter to it. If you loved Divinity, you'll love this one too!)
(( see here for instructions on how to set it up, follow said instructions, do NOT run a GOG version. If you DO have one, read my last post on said thread for further clarification))
