If you love Skyrim, I advise that you get Oblivion as well with the DLC's. Trust me, Skyrim is a great game, but when you really look at it, Oblivion is one of the only games better than Skyrim that I've ever played. Oh, and if you can stand terrible graphics, get Morrowind. It's considered to be one of the greatest RPG's of all time, and it has some of the most memorable moments (www.youtube.com/watch?v=NnFUqAjp-pE) and music (https://www.youtube.com/watch?v=nJD-Ufi1jGk) ever, as well as the greatest story to possibly ever be part of a game.
IMO, Skyrim is a great game, but Oblivion surpasses it by miles. Not saying Skyrim sucks, you know, but Oblivion..man oh man, Oblivion is one seriously insane game. The quests will blow you away, as well as more character customization than Skyrim. Not only that, the graphics are pretty stunning for a 2006 game. The main quest is garbage just like Skyrim's, but the factions and side quests you will never forget. (I'm not kidding, join the Dark Brotherhood, you will see)
But if you have played them games already, well...I feel stupid.
Anyways, apart from that, great list! Of course there are some games not in here that dumb it down a bit, such as Neverwinter Nights and Mario (JRPG technically), but nevertheless, great job.
