VAC is bad and most server admins are retarded. I see cheaters every day in css, but why does it matter? I didn’t play css for public and any good game has a 3rd party anti cheat, which works well.
A game i’ve been playing for a while now “Global Agenda” is a bit like TF2 but it’s easier to carry a team in it, they don’t use a good anti cheat and the people that get banned normally have had a video sent in of them playing [no demo feature so it’s awkward].
The thing that worries me the most is when i got banned from Global Agenda for being too good aka “cheating” when i wasn’t, i did however get unbanned after a month, in that time i had sent 15 emails and even uploaded videos of me from real life. Most developers don’t understand the competitive side of games and how good players can get, i honestly don’t think we will ever see anything like cs1.6 or quake again, just because it doesn’t appeal to the masses.
