Facebook game The Sims Social is quickly nearing 30 million monthly average users, just a month after going into beta.
The game was launched just three weeks ago, and saw an increase in 7.5 million users in the last week alone, Gamasutra reports.
The game is an adaptation of EA's Sims franchise, and has become the fifth biggest game in terms of audience size on Facebook.
Recently PopCap announced it was interested in working on existing EA properties in the wake of its buyout.
