Forum:Singleplayer, single player or single-player?

Whilst browsing through articles, I've noticed that "single player" is written in three different manners: "Singleplayer", "single player" and "single-player". I understand that normally COD:BB would tell me to change it to what I feel is better, but I feel this is a bigger issue than for just me to decide upon. Now time for my proposition: Uniformize one of these spellings as having many different form seems, well at least in my opinion, rather unprofessional. I would like this thread to be used to decide if this is or is not necessary and if it is, which spelling should be used? Thanks for reading and considering.
