Over the weekend, Valve's DOTA 2 broke the record for most concurrent gamers playing on Steam. It surpassed the previous record set by...Valve's DOTA 2.

On Saturday, 328,713 people were playing the company's still-in-beta MOBA title. At the same time. That's crazy.

Not as crazy as the numbers of its main competitor, League of Legends - which claims to have over 500,000 concurrent players in just one region - but still, impressive.
