24/7 power exchange isn't a game.
Would you call a traditional MF couple, like from olden days up to the mid 1960s, where the wife has promised to "obey" her husband and defer to his final decision, game players? Or just following what they think is the proper, even Biblical template?
Ds is kind of like that, only spelled out, not as God's plan, but as a choice made by 2 empowered loving rational beings. (And of course, the sub can be male and the Domme female.) BDSMers, like poly people, seem to be forced to have more insight into themselves and their relationships than mono MF couples.
Comparing the dynamics of a loving relationship to a hobby seems just a bit dismissive. Calling it just "fun" is kinda ridiculous, imo.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
