i am a member of this community and am glad to help keep the servers running and free of shitheads. however, the only thing subscribing to a p2p game would do is put money in the hands of the company that makes it. at ibis, my money goes to improving the servers directly.
also, 10-15$ a month is quite a bit to me, considering how i'm at school, paying rent utilities and food. the money i build up over my last co-op needs to last me another 4 months, until my next co-op cycle starts, so i really don't have the cash to spare since i'd rather not be forced to ask my folks for more money than they're already paying for my school. plus, i don't have the time to make it worthwhile. my grades are bad as it is, and adding another distraction on top of tf2, css, LoL, Skyrim, Stargate, and anime is not a good idea.
