May/June last year I played about 70 hours and had gotten to the Kaer Morhen quest line on 'Just the Story' difficulty.
This month, I played through the rest of the base game and DLCs. Then went back for more and played New Game+ on Death March.
So yeah. I really enjoyed 100%ing this game.
The only achievement I really disliked was the Master Marksman achievement. It requires 50 headshot kills with the Crossbow. Worst achievement.
If you end up going for 100%, I recommend making sure you check a guide for Gwent and missable cards. I missed one in my first play through early, so had to do this achievement in my Death March run. Death March wasn't to hard in New Game+ as Geralt, as I had fully geared him and went an Alchemy build.
Only real struggle with this build was the last boss battle, which I died repeatedly in.
My issue was playing as Ciri. I ended up modding her, because they don't allow you to change skills/gear etc., and the combat is already awful enough on K&M. :(
Mods I used and recommend:
• The Witcher 3 HD Reworked Project
• All Quest Objectives on Map
• Over 9000 - Weight Limit Mod
• High Level Ciri I went so well with Ciri in Death March until the Crone fight. Then gave up and downloaded a mod lol. She hits like a wet noodle and would die in 2-3 hits…
• Master Marksman Achievement Tracker (Worst achievement, this made it bearable…)
Also if anyone else wants to 100% this game - for Master Marksman, don't do this achievement in New Game+. Load a late game save and go back to Velen and slaughter low level bandits in Devil's Pit. I originally tried this achievement at my endgame New Game+ DM save, and it took so long to get a few kills due to having to get the enemies health down so the arrow would be able to kill them. In comparison when I loaded a previous save, the bandits died with 2 arrows.
It was interesting seeing different choices through my second play through. I tried to change most choices up. I feel like my first game ending had a better world, bitter sweet ending for Geralt and co., while my second play through the world ended up hellish with a good kind of ending for Geralt and co.! I also noticed some quests I did, choosing another option pretty much finished the quest straight away so you missed a chunk of content. There was a side quest I remember with a woman's sister who went missing. In my second play through I took the easy way so missed what happened. Some quests however ended in a similar way, just got there differently. The Tower of Mice quest with Keira Metz for example, both endings were essentially the same result, but I enjoyed both in how they got there!
Speaking of different choices: I went back to a previous save to get the second ending achievement for Blood and Wine DLC - Wtf was with that sex scene haha
I really enjoyed in my New Game+ play through seeing a familiar character from Hearts and Stone DLC in White Orchard - someone I had not even noticed previously.
Oh and SO many screenshots. I used Nvidia Ansel to take them, as Witcher 3 doesn't have a Photo Mode unfortunately. I tried mods last year when I played, but they just weren't great.
