Enjoy!
It's very easy to screw up your experience the first time, so follow these rules:
- Try not to do the main story quests until all side quests have been taken care of. Not doing this can present issues later, as the game is divided into 3 chapters and you might close certain side quests off by moving to the next chapter. You also might suddenly need a character that is dead or otherwise unavailable.
- Talk to everyone you come across and to as many bystanders as possible.
- Grab the quests off the noticeboards.
- Never pass up an opportunity to play Gwent.
Here's a big one, to avoid getting a crap ending through no fault of your own:
- The game is weird about how you treat Ciri. Don't coddle her, and let her blow off steam when she wants to and don't accompany her to a particular witch meeting later on when she asks.
Apologies for the minor spoilers, but it's better than feeling like you should replay the entire game to get a better ending.
You're just slow lol. I've played a similar amount of time and I am well into my second playthrough.
