I don't think that has any merit, Paradox have launched and developed a bunch of successful (in their genre) games, and owns multiple studios while doing the publishing for even more. It's a successful company and would have been without Cities: Skylines as well. Probably parent meant the developer of the game, Colossal Order, which only developed Cities in Motion before, which was successful in it's own right but not on the scale of Cities: Skylines. But then "other X games wouldn't have existed otherwise" doesn't make sense, because Cities: Skylines is the latest game they've launched, and it was in 2015.
