@ocean@niu.moe The game is so massive it can get a bit intimidating, so I think they made the right choice having fog of war on the map and adding marks on it only once you get close to them.
The story is pretty nice, but even though some choices you make end up effecting you 10 hours later they don't matter in the end. The choices are there just to be there.
Some of the side quests are cool, some are even short stories on their own, so they are definitely worth doing even if some turn out to be fetch quests.
The amount of jank is surprisingly small for a game of this size. I think the most common bug was trees or rocks floating slightly above the ground.
Did you also play Lost Stories Of Greece? They were a free update to the base game.
So far I played the first chapter of first DLC and it looks like the DLC will show you the unexplored parts of the map, however I'm not impressed with it so far. I'm more looking forward to Atlantis.
