Minecraft is the best selling game of all time[0] and while it's been marketed more since Microsoft purchased it, the first million sales happened within 7 months of charging for the game. Just over a year after commercial release it hit 10 million sales.
This was not a period of Minecraft marketing. Most sales were due to people simply seeing others (friends, YouTubers) playing the game and wanting to try it themselves.
