Any of the shadowrun games.

If Tyranny/Pillars of eternity has wet your apitite how about any of the Shadowrun games? Great writing, good gameplay, and you can get decently far with little learning curve (i.e. not so many tooltips/advanced mechanics). Would be a great to see you try one. You do NOT have to play them in sequence, so Dragonfall or Hong kong might be better mechanically since Harebrained had time to work on the gameplay between the games.
