I'm a completionist gamer, but then again, isn't everyone when it comes to CD Project Red games?
So my answer is likely going to sound simple. EVERYTHING.
But it'll likely play out like it did with The Witcher 3.
I remember deciding to do one kind of quest in Witcher 3 and then just, just LOSING myself.
Going down a road of adventures which just never end being incredibly absorbing.
I hope to be able to do the same with Cyberpunk 2077.
And just like in The Witcher 3, when its all said and done, I will probably be taking one final thank you tour through the whole game, travel to each part and marvel at the incredible world CDPR have made once again.
