I've been playing Witcher 3. So far, it seems great. The graphics are fantastic, the combat is fun, the world is huge and the narrative is interesting. My only problem is that it's so intimidating. I only have a few hours to play every now and then, and there's so much there to see and do. Sometimes I don't want to play cause I don't have enough time to really get into it. So it's going very slowly for me. Still great, and I'd definitely recommend it. I started Last of Us remastered for my first replay since it came out in 2013. For when I didn't want to commit to the Witcher. Wow. The game immediately reminded me of why I loved it. It just tells its story so well. Unfortunately, I had controller issues. So now I've been playing God of War remastered for an hour or two each night. Nice nostalgia. Seeing how it holds up. So far, it holds up pretty well.
I have the same conflict with Witcher. I want to play it so badly, but then I get into it and it feels like there's almost too much going on. I'm worried about progressing through the game because I don't want to miss something, but then I end up pretty much going nowhere. It's gorgeous though.
It's a pretty big time commitment, but it's definitely worth playing. I'd say try to knock out some of the main quests on a weekend or a time when you have a couple of hours, and then go through the side quests and witcher contracts that are within your level range. Those tend to be shorter, plus they're generally really well developed and fun. So doing it that way I'd imagine you could get pretty solidly through the game in a couple of weeks.
