Rust IS in depth. I would say the crafting is more than a little extra added. It's a different type of game, more about survival from the ground up whereas DayZ is more of a scavenge and survive from human predators game. Minecraft is in a different genre completely. 7 Days to Die is alright but can't keep my attention that long. The whole block style gets to me and I haven't played with the most recent updates but as I know they've just made it harder basically...which I don't mind but it just isn't for me over the other two above.
