You are DEFINITELY not alone. I love this game too, and have never played a game so many times and for so many hours.
Play it again. Choose different character options etc. Ive played through a ton and am still finding new stuff and having a completely different experiences each time. 300+ hours later.
As for multiplayer, you can try creating 4 custom characters using instead if you don't have others to play with. Let me know if you are interested in that.
