So, he pretty much said that if we combined the numbers of steam players and players that play throught the old, normal client, the game would sit in the top50 of steam.
Lets check then, shall we?
He said "firmly" so let's say he means top 40-50.

These numbers are from "right now", which is around the highest phase for every game on steam.
tl;dr: MWO probably has about 8000-6500 peak players every day.
Can anyone remember what the counter showed during close beta? Were the numbers higher or lower?
