If you just started playing I would say, play the game at your pace, there is no time limit, no need to finish until you are ready... progress as you want, get some hides in the meadows, then kill the 1st boss... then get bronze until you want to get the 2nd boss... no rush, hell I spend too much time watching the sunset while having a cig, there is no rush.

My point is, its fun to play with mates, but its also a lot of fun by yourself while you wait for mates.
