"One more turn/match" is bad enough for sleep & life when it's not supercharged by actual gambling mechanics designed by a team of professionals to keep you playing. Yeesh.
That is important to say. I have definitely stayed up all night playing games with zero extra monetary support. Those nights are infrequent and devoted to games I absolutely enjoy. Once I get my fun from them I go back to sleeping normally. Free to play games override this sense of contentment.
