When releasing a game, under what circumstances is it a good idea to include an end user license agreement and why? In my case, I have made a simple Android game that I want to sell on Google Play. Do I need an EULA for my own protection? Google gives the suggestion that you "may want to prepare an End User License Agreement (EULA) to protect your person, organization, and intellectual property." The Google / Google Play terms of service seem to have a warranty disclaimer and limitation of liability clause that protects Google itself but, as far as I can tell, does not protect the app developers. Thus, I would think all app developers would want to include an EULA to obtain this basic protection. However, I think most Android games, even professional ones, do not require you to read an EULA before using them. Why is this?
