Their crafting, the whole building thing and resource gathering remembers me very much of some parts/systems of Ultima Online. Something we have not seen in a while.
The whole idea of players able to change the world, gather everything you can see, also hints me back to Minecraft, which has been a fiber lately. Xsyon looks, for me, like a scaled up Minecraft, which is also good.
So, yes. I think it is good we see something like that showing up again. Might wake up some developers.
But i do also agree with a few others here. I think their pricing is wrong. They are pricing their game, like if it was an AAA title, which is not. I would be testing if they adjusted their pricing. Get it to 30€ + 9,99€ monthly or free download + 9,99€ and a lot of people might reconsider it.
