Max, it seems that you are mixing up the idea of "playing something" Entertainment comes at all levels and cost. Some would say going to the movies and spending 100$ is crazy because it will be out on DVD for 20$ in a month or buying a 100,000$ sports car to go and buy groceries is insane. Some people just may find playing a phone app entertaining and are willing to spend on it. Just like with everything else in life, as long as you know it's just for fun and you buy responsible, and that may be at different levels for people, live and let live. Some might say your time is much more valuable then any dollar figure you could mention and with that you've been playing and on this forum for how long?
