That doesn't contradict my point that ustwo might not need to make ten times more money than they spent developing the game to run the company (and to be considered succesful).
I was specifically referring to the statement "and it DID make them rich". That statement I think is provably false. Depending on how one defines rich of course.
There are many ways to define success. ustwo is a 300+ person design company. Their mobile games could lose money but still be considered a success.
