If you think libgdx is low level, your already f**ked.
Do a little reading, so far it sounds like you just want the easy route.
No such thing.
Libgdx is low level compared to tools like Unity/Unreal Engine, yet several games that use those have been extremely successful. How can you say someone is "f**ked" just based on their choice of libraries? And "easy route" sounds like something an (immature) C++ programmer would say to a java developer. Come on.
He came on here and asked a stupid question, hell he even answered it himself.
Immature? Yah maybe, realistic? Most likely.
He wants to target android and iOS, he had not mentioned anything about his prior coding experience, he seems to think that sprite.draw() is complicated.
All I see from reading the OP that he wants the fastest, least difficult way to pump out an app and milk the cash cow, the mobile market is being destroyed as it is.
If he feels like posting with some passion about the language we use here, about his goals and less about what can get him from A to B without the effort.
Then I will post a helpful reply, sorry. Just the way I see it. Harsh but at least I don't sugar coat it.
