SOE president John Smedley announced on Twitter today that 120,000 new players signed up for DC Universe Online on PC since going free-to-play on November 1. Smedley also revealed that the game’s number of concurrent users increased 400% during that time. Numbers for the PS3 version were not provided. The game has seen a few server issues since Tuesday due to the influx of new players, but hopefully Sony will get things sorted soon.
