What cross-platform 2d-3d engine do you recommend?

Question

C++ / C#

There have already been similar questions, but I did not find a definitive answer.
If my main mastday system (brr) - would take Unity. There is not much money to buy a decent poppy.
What engines allow you to normally develop cross-platform games (preferably win, linux, android and the ability to later build for iphone)?
For 2d, I more or less liked cocos2dx, although they have a lot of jambs with outdated documentation. Maybe there are some other great ones?
But for 3d, I couldn’t choose anything.
Specified c ++, but the language is not fundamental.

Answer 1

So that both 2d and 3d and cross-platform (including Linux) then only unity. There are no real alternatives. Is that a game move from the havok team (I forgot the name).
How is this related? Unity plows on Windows too, but you can’t compile under the bullseye on anything other than poppies.

Answer 2

You can also try looking towards the marmalade. c++. Only under Linux does not collect. Under IDEVICE it is possible to collect in Windows.

Answer 3

One more question will not fix the situation. No one will invent anything for you personally. You can go down to earth. You are not special. In the same as everyone else.
gamedev.stackexchange.com/questions/1265/must-read... You can start here. Or google mono 3d engine. When you review all 5-7 possible engines and run into problems that you will be too lazy to solve (usually this is the complexity of development), then calm down.

Answer 4

Unreal Engine 4 supports many platforms. But development on Windows or Mac.
For 2D: cocos2d-x, Love2D, Corona SDK.

Answer 5

Judging by your wording of the question, Unity is probably better off not finding anything.
