Sorry English is not my first Language.That was difficult to read but I think what you're saying is that they quit because the game was hard? The problem was, and why they all quit like me, 99% of the crafting was useless. You could live in a 7x7 wooden base from day 1 to day 9999 with no worries of survival or zombies destroying you. You could live on a wood platform on a tree. You could live forever in the ground. Food wasn't an issue, like nothing else was. They didn't find any point in survival since... all of that grinding led to the same result no grinding would -- you're perfectly safe.
No what i wantet to say was this.
Many People quit playing in Alpha 15 and 16 and are now back playing possible stoppped in 15 and 16 cause it was not enough PEW PEW and not enough easy mode crafting , leveling and Learning of Recipes.
Now in 17 most Survival is only PEW PEW against zombies get xp get lvl up learn new recipes with skills.
Before it was Learn Recipes with looting and searching books, digging to get better with tools and such stuff.
So possible before it was nothing for the Shooter People but now its only for Shooter People and not really for Builders, RP Players , Miners and others.
