I played it just by myself, and I imagine having a friend you always play with being the funnest way to play, but I had a blast playing the game just by myself. The game is pretty much all playable single player. So def get it.
VJ first since I think it's my favorite of the two and then if you really enjoyed it then go for the BR one. They're both fun to watch and I stuck with VJ till they finished, then watched BR and I found it really fun to go back and see their reactions.
Like everyone else has said price drops aren't coming anytime soon. I own a PS4 and I can say that it's still very barren out their as far as games are concerned, although the indie games help, so if you don't mind that then just get it now.
