Well I am an pack animal myself and enjoy playing games with groups. I found that playing Wurms Online alone was also rather fun, while time consuming it did has some satisfaction to even do the smallest task by yourself and see you build a small deed all up by yourself. Find your own mine, terraform your own land, farm your own food etc.
A discussion with is similar to this is being discussed here and in this thread we already concluded you can not set up a temporary camp.
However is it possible for a player, without a tribe, to create a small camp, small farm (after we get there though evolution :P), etc to sustain himself and how "easy" would that be to do? In Wurm Online it was relatively easy, while it was hard work it was possible to even as a new player go out and do it and maintain every building, fence and farm to sub stain one person.
