Indeed it’s something can find hardly enjoyment in, but plenty of people do love the scene you described. Casual, HOGs, Walkers and the like have quite sizable player base, for me those genres often tend to be not so interesting, besides walkers sometimes and some rare cases in casual. As example of good walker Outer Wilds was very impressive, as it did well balance several things while in it’s core it still feels like a walking sim. 15 hours already sounded way too much what Eidolon would offer, 50h for sure would be quite a thing to deal with personally! :D

Honestly quite many open world model games can struggle at those hours no matter if they are in other genres, as often the maps are just filled with empty space you spent time walking around. Starting to become welcoming more linear games due this later on. Metro Exodus for example was downgrade from previous games largely due open world slapped in it! x.x
