I've been busy with The Witcher 3 for a while now, and considering how frikken massive this game is, I'm probably going to still be playing it for a long time still. And then I have the two expansions to play though as well.
Amazing game, but I like to do all the stuff there is to do, and there is just soooo much to do in this game, and it's not just repetitive filler stuff, it's cool side quests that are all fun and interesting and different.
