Well here I go again. I strongly disagree even though I'm outnumbered.
Morrowind GOTY has the complete Morrowind with the added chapters but it's still Morrowind. If you buy the expansions separately you still have Morrowind. You can't have the expansions without Morrowind so it is just an extension of the same game. In fact when you start the game with either Tribunal or Bloodmooned installed you are taken to the Morrowind launcher and you cannot go directly to either expansion you are started in Morrowind and you have to work to get to either expansion, so I still contest that they are all part of one game.
If that's the case then Sacred Gold should be treated the same way since it includes Underworld, which is an expansion. Witcher enhanced also includes two new adventures and with the latest patch includes 6 new adventures.
My point is that if you need the basic game to play anything then they should all be included in the basic game.
But what do I know I'm just old and had a bad day.
You make the rules and I'll follow.
