OK, so I just added $15 to my steam account, but bought something on tf2 and now have $14. What should I buy? I don't really want an indie game, and would prefer if it was something at least somewhat cheap, and won't use up my entire budget all at once. I am thinking CS:GO, or some other game I can use in Garry's mod, but I don't know if I should worry about that or not. Hit me some ideas, and tell me their prices.
Oh, and idk if you people will actually go against this, but
please, steam games
only. 
Edit: Also, I would prefer to wait if nobody really has anything good, but idk... then, or now? Anyways, I'm off to bed for tonight. Hopefully there will be tons of replies tomorrow. :D Back.
