That's beside the point.. The reason i mentioned the money/cost of Unity was people complaining about the $500 to remove a splash with Cocoon IO from a single game.
If those same people happened to want to use unity.. they would pay far far more to do the same. MAYBE eek by with a 1 month subscription and only pay $225 but that would be a 1 month window.. a 2nd update would require another $225.. etc etc.. and each game would require the same.. and i'm not sure if a user could do that long before Unity themselves would come down on a developer for not keeping their 12 month obligations.
read this https://store.unity3d.com/subscribe 12 month obligation.. i don't know what the penalty is for cancelation but the point is that you're breaking your word with Unity.. I don't think they would like you to do that.. that means a 1 year subscription to unity pro with android and iOS cost $2700 x per year.. forever.. or a 1 time $4500 payment.. that will eventually become outdated.. you're buying Unity 5 today.. but next year when Unity 6 comes along.. you'll be left behind..
yikes I read the fine print:
"By purchasing a subscription with Unity, you agree to the following terms:
The minimum commitment period for a subscription is 12 months. You cannot cancel your subscription before its expiry date.
You are legally obligated to pay the full amount owing for the 12 month subscription via monthly payments."
so yea there is no cheap way to get unity splash free.. $2700 is the cheapest option.
people are making tons of games with unity WITH a splash not making $100,000 or paying for pro and making money.. Cocoon IO's splash is no different. if your game is good you won't need to remove a splash. you will make just as much money with or without it.
