I remember them saying they dont wanna do open world games around the TLOU1 time.
Id trust Naughty Dog to do a good job of an open world game. FromSoft did a great job and in general I like alot of the elements an open world bring, it has its down parts.
Naughty dog are known for there animations, voice acting, attention to detail and roller coaster action, so if they can implement that into a large team for an open world game they could do some great new stuff
Im looking forward to the TLOU Online game, and if the rumours are true about the part mentioning: A single player like experience in an online game.
But I dont want them to think and feel they are forced to make an open world game, just do what you do best
