So, I THINK I'm done with the base game in Witcher III. I say that because I did the big showdown at Kaer Morhen after doing a Blues Brothers/Avengers of putting the band back together, yet it seemlessly went into the next mission of taking the fight to the Wild Hunt and I killed one nasty big dude at the summit of Bald Mountain and killed two of the three crones with Ciri. This got me thinking. On this playthrough I decided to kill the evil spirit trapped in the tree, yet while at bald mountain I picked up some literature that said that the spirit in there was one of the ladies of the woods. I wonder, had I freed it would the fight gone differently...
Also, Geralt mentioned something practically off-hand which I found very intriguing. He said he recognized one of the men with Eredin from HIS time riding with the Wild Hunt. Wait... WHAT!? When/how did that even happen? One of the things I like about the game is that, while it is a direct sequel, you didn't have to play Witchers 1 and 2 to know what goes on in this one. But a surprise like this does make me feel like i missed something somewhere.
I also got a bit of anxiety, because I originally wanted to do all possible side quest, treasure hunts and witcher contracts, before finishing the base game. That included clearing the map of all question marks and there were several caves, guarded treasures and monster nests/dens in which I confronted monsters way stronger than me. So I was greatly bothered seeing a great portion of the map, both in Novigrad/Velen and Skellige, unexplored. However I am now level 31 (I entered the Isle of Mist at 26) I'm confident in being able to clear most of the maps now.
On an amusing note, a couple of days ago my GF asked me, "So, how long is this game?" "From what I've been told about 140 hours on average, why?" "Well, because you've been at it every day almost all day for a while now (about a month) and you're still not done." "Here, check this out," I said as I showed her the map with all it's question marks, the list of side quests, contracts and completed quests. "Now," I continued, "I don't HAVE TO do it all, but I want to. When I play it a second time I'll know what is worth persuing and what is best to ignore." All she said was, "Hmm, I'm going upstairs." She normally likes watching me play, but she HATES RPGs, she said, "OMG they're STILL talking!? Is that all they do?" "Um, hun, it's important plot what's going on right now." "It's f'ing boring." So, don't know when she'll join me again lol.
