I guess it depends on what sort of game people think 7d2d is. I've played everquest in the past for 10 years. Spending an entire week, or month, to level 1 point, was the norm.
72d2 right now, doesn't have "end game content". It has limited content, and limited challenges, that are highly customizable.
Is this a grinding game, where you need to mine and dig and loot ammo non-stop for 6 days, so you can barely survive the 7th day?
What is the purpose of repeating this pattern?
I guess in my mind, 7d2d seems like something you'd play for a few weeks, 'master' that world, and then start a new game sometime later. In that scenario, I'd expect to make more progress each night. In a few weeks, I'd like to have basically "everything".
Why would I spend 3-4 months playing a game with zero end game content? This is, or isn't, a game like a mmo.
People that are comfortable with the current pace, I'd love to hear from you what enjoyment you get out of the game after playing a world for 6 months. OK, you've got all the gear, OK, you've got all the weapons, then what? Does it feel fun just fighting off the zombies week after week?
This game either needs to focus more on casual replay worlds, or needs to focus on progression and end game goals.
