I was a big fan of NWN so when NWN2 came out I played it and I really enjoyed it, I missed the Underdark but the story actually had better characters.
Fallout: New Vegas was outstanding, the ammount of content that game has, both from the developers and the community, you can basically play that game forever.
It reminds me why I was such a big fan of Neverwinter, the NWNVault, the CEP (community expansion pack) and the ability to create your own content with the Aurora Toolset, infite replayability.
