I assumed that everyone with access to a PC would have played Portal at this point, but it seems this is far from the case, at least if Portal's all-time concurrent players are anything to go by. According to Steam Charts, the record for Steam player concurrents stands at just 3,370 players, which is apparently a quirk of the game launching before Steam kept accurate player records.
Later today, a group of Valve superfans hopes to change this. Valve fansite LambdaGeneration, in association with major Valve YouTubers Noclick and Radiation Hazard, is running an event called #RememberPortal, urging players to band together and push Portal into an all-new dimension of concurrent player counts.
