Well, I started to look for another engine when I saw V4 licences. Second version of licences are way better than the first, but it destroyed my dreams about selling my game on AppStore. I just can't pay 490 euros for engine where you have to pay another 490 when releasing a game. It's too expensive when your salary per month is 300euros and you must pay half of it for rented room (not even speaking about going to cinema or buying a book to read). I was advising to create separate licences for users and companies but no one listened.
Let's look for another engine and what you can get for simmilar price:
Game Maker Studio Master Collection - you can create any kind of 2D game on any platform without coding, just scripting.
mayor point to it is you only pay the license fee once and you can make whatever you want with it and not worry about fees and stuff, plus you can make lots of different kinds of games with it including 2D point N click (Leisure Suit Larry 1 remake was made with it and works great) and also the users can expand on it, BUT it's not an easy application to use and you may end up paying for extra plugins.
That's greatest thing about it. You pay once, and it's very fair. Yes if you want more functionality you can buy plugins, but you can make games without it. Yes, it's not an easy application to use, but I like the challenge, and im not limited to point & clicks only.
NOW, I was looking at Unreal Engine 4 today and was quite intrigued/impressed by the "Blueprint" feature, seems to be easier to use and seems to be a bit tailored to artists with limited/null scripting knowledge.
On top of it, it has what it seems to be an incredible deal of a license, it has a monthly fee of $19 BUT apparently you can use the engine by paying the first month and then you can cancel the subscription (which covers mostly updates) and still be able to use the software without restrictions. You only agree to pay 5% of your game's selling price in order to use the software... I think that is quite a deal even more considering how powerful the Unreal Engine is.
Another great engine and you can do everything in it. UE4 has good future, most of game developers will use it.
