@SirJames; Other games had secrets but not in the abundance and with no clues they exist like in Super Mario Bros which made it a phenomenon in school culture.
As for less dungeons, I dont think so. The game map is so huge filled with dungeons there are about 50 dungeons or at least what i consider to be dungeons ranging from pretty huge dungeons to smaller ones. As for exploring every nook and cranny, I find that is the beauty of the game, its so huge that you could do that, you could spend a lot of time exploring, you could just do the dungeons.
As for multiplayer I really enjoy it. Despite it being a little harder in multiplayer(the person who joins someone else's game gets half the flasks), there is a certain thrill of getting invaded and beating those people. More so when you are running out of flasks. That said there are some broken systems which make some of the invasions not fun.
And the troll messages are whatever though later in the game because the game gets harder, people are putting more helpful messages. And even the troll messages have people saying "liar ahead". That said i do enjoy watching people jump off to their doom(red patches), some of them are in unexpected places.
