HunchBluntley: ...And on what the specs are for those ten computers he mentions. Unless he's rich, it's not likely that they're all bleeding-edge PCs. (Unless his friends all brought their own machines over and left them at his place for him to set up.)
pitchman: All of the PC's are i5's with 8GB RAM and 128GB SSD. They have Radeon R7 Graphics adapters. I have 20 of them connected with gigabit NICs through a Cisco Router and I have an HP server with 64GB and 3 TB of storage with the newest Intel Xeon server processor available. I will only be using 10 to play on, (Unless there is a game that allows 20 players.)
You mostly looking at competitive, co-op, a mix? Shooting, racing, strategy, etc?
(Note that I,
personally, won't have a ton of recommendations, since I neither play multiplayer on PC, nor have I played many games from here that have a LAN option; I'm just trying to get the ball rolling some more.)
