No, they didn't ALL argue they would build underground bases. I have called for digging zombies because underground generally is boring without them.
If it was too boring for you in the underground then you could also simply build on the surface. You had the choice.
You also didn't have to make a mine but you could get a lot of resources from above ground sources like the small rocks or the above ground resource nodes.
I've been driving around a lot and mining resources above ground and I've been sometimes running in a wandering horde. A lot of times it was a zombie dog horde.
There are people who appreciate a little boredom. Some people just want to relax sometimes. That was taken from them with the decision to let the zombies dig.
And in A17 and 17.1 the decision was also taken away from them.
I had several bases in the A16. Partly underground and partly above ground. But they were all just working bases. I also had bases that were only there to fight the horde. These were all bases above the ground.
As long as the zombies could not dig the player always had the choice whether he fights the horde or not. I've always decided to fight the horde, but I don't blame anyone for saying they don't want to fight the horde. That's their decision.
In 17.2, players again have the option not to fight the horde by turning off the bloodmoon horde but only as single players or if it is their own server. If the play on a public server they only can log out before the horde starts.
I never said I would build bases down there. Just to clarify that I don't feel I need to justify myself here.
And yet you're responding to this part of the posting. So I must have hit a nerve.
BUT recently I got two ideas for underground bases and wanted to try them out. Yesterday we (co-op group of four) tested this design (the pictures are from AFTER the horde night)
It's a pitfall, not a classic underground base.
A classic underground base has only one hatch on the surface and the rest is hidden under the surface. These bases are also not meant to fight the horde but to work and store raw materials.
These bases are very popular with PvP because they are easier to hide.
But this pitfall shows very nicely the problem with underground bases. You never know where the zombies are digging. Accordingly, the defense is difficult here.
