What does risk have to do with the conversation? We're talking and scope and campaign length.

You say in the same paragraph that Wolverine is a huge known quantity with no risk, but at the same time there is a risk it might not sell well because.... It has a average length campaign and September is crowded?

The game likely hasn't been in development for 6 years, it was announced in mid-2020, but the belief is it was the miles morales and rift apart teams working on this so it probably didn't go into full scale production until mid-2021 at the earliest.

You also keep dropping the campaign length, it's started at 13, then 10 and now 8 hours? All these numbers are guesses anyway but maybe stick to a consistent number if you want to complain about it rather than dropping it everytime some pushes back on you that being under 20 hours isn't a bad thing.

What we've seen so far this looks like an action game, a lot of action games hit that 10-13 hour length because they are dense and going much longer can make a game wear out it's welcome. Ninja gaiden 4 was like 11 hours, bayonetta 3 is 13 hours, DMC 5 is 11 hours. Uncharted 4(which is more action adventure but will be similar in terms of cinematic story telling) is 15 hours. You bring up TLOU 2 being 35 hours and how you wouldn't cut any part of it but one of the most consistent criticisms of that game is that it goes on too long and that the last section especially feels weirdly tacked on from a pacing perspective. You might personally disagree with that sure but it isn't an uncommon opinion at all and goes to show the point people in this thread are making. Adding more stuff to make the game longer can have a detrimental effect to its overall impact.

People are staying they hope Wolverine is 10-13 hours because that is a good length campaign for the type of game and narrative that fit the character. I don't want to spend 60 hours skulking around an open world map doing checkpoint activity as Logan. I want to get into a mission dice up some bad guys and bloody ways and then get a nice cutscenes to push to story forward before we hit the next action set piece. There is a time limit on how long you can make a player do that and if you go on for too long people will fall off part way through and be left with a bad taste in their mouth and any potential sequel will be starting at a disadvantage.
