The RPS reader - a discerning, beautiful creature raised by feral desktop machines in the jungles of the internet before being discovered by a pipe-smoking explorer in 1956 - likes to play videogames in the company of like-minded gamers. It was to this end that we erected the fantastical edifice know as the Game Clubs And General Sociability Ok forum. It is this distinguished public space in which you can find your way to games of Terraria, SWAT4, Warframe, Battlefield 3, Neptune's Pride, Dominions, Arma, Guild Wars 2 and numerous others. The world is your oyster, where - for the sake of this figure of speech - oysters represent various possible multiplayer gaming opportunities.
Go play! And perhaps visit the RPS Steam group, should you be so inclined.
