+1 for solo. Being able to reinvent oneself and artificially increase the difficulty (by making choices usually inappropriate for the type of environment you're in) is fantastic. Been having a heck of a blast. Much to my surprise, multiplayer takes a lot away from the feeling of exploration and, worse yet, discovery. Very much to my surprise, I found solo much more rewarding. 630 hours in and I still cannot stop. Incredible value for 13.99 €.
