Minecraft is the best selling video game of all time by over 100 million copies; it's an outlier. Aggregating multiple games across an IP franchise doesn't make sense because it's often the same people buying every new version (this is true of movie franchises too -- it doesn't make sense to combine the ticket sales for Infinity War and Endgame as though they are independent events, e.g.).
Even Minecraft doesn't compare, though. 238 million copies is a lot, but big blockbuster films sell 300+ million tickets, and then get millions more new views via rental, home purchase, etc.
Most games, even the biggest ones, don't sell more than a few million copies -- Skyrim, which is one of the best selling games ever, has roughly 30 million sales. That's a drop in the bucket compared to blockbuster films.
