My brother (Nokturnus) and I play the SCPT demo often and do fairly well due to the hours we put into it, and our use of good teamwork.
My beef is how many players will simply leave a game as soon as they begin to lose (die a few times or see a few ND133s get hacked). We literally run into this problem at least three out of four games, and it gets old fast.
It's really frusterating to have to play a Merc and be looking forward to your turn as a Spy, only to have the host leave because he wants to play someone with less skill.
Anyway, I find that very few players conduct themselves in a mature manner, and the ones that will stay in the game even after losing a game are even fewer.
This evening I played against Darkenedflame and Onyblonx. The game was close but my brother and I won the round, only to be stunned by their response. These two awesome players said they didn't mind losing now and then, that it helped them realize there was always room for improvement. They stayed and we played several more rounds.
My hat goes off to these very skilled and mature gamers, who deserve to be respected if you're on their team, and feared if you face off against them
