I've worked with Marmalade and I found it satisfying. Although it's not free and the developer community is also not large enough, but still you can handle most of the task using it's tutorials. (I'll write my tutorials once I got some times too). IwGame is a good engine, developed by one of the Marmalade user. It's good for a basic game, but if you are looking for some serious advanced gaming stuff, you can also use Cocos2D-x with Marmalade. I've never used Cocos2D-x, but there's an Extension on Marmalade's Github. Another good thing about Marmalade is it's EDK (Extension Development Kit), which lets you make an extension for whatever functionality you need which is available in native code, but not in Marmalade. I've used it to develop my own Customized Admob extension and a Facebook extension too.

Edit: Marmalade now has it's own RAD(Rapid Application Development) tool just for 2D development, named as Marmalade Quick. Although the coding will be in Lua not in C++, but since it's built on top of C++ Marmalade, you can easily include a C++ library, and all other EDK extensions. Also the Cocos-2Dx and Box2D extensions are preincluded in the Quick. They recently launched it's Release version (It was in beta for 3-4 months). I think we you're really looking for only 2D development, you should give it a try.

更新: Unity3D最近推出了对2D游戏的支持，这似乎比任何其他2D游戏引擎都要好，因为它的GUI和编辑器。物理，精灵等支持是内置的。你可以看看。

更新2 Marmalade将停止他们的SDK，转而支持他们的内部游戏制作。所以依赖于它不是一个明智的决定。

LibGDX is one of the best engines I've ever used, works on almost all platforms, and performs twice as fast as cocos2d-x in most tests I've done. You can use any JVM language you like. Here's a 13 part tutorial in Java, and here's a bunch using jruby. There's a good skeletal animation tool that works with it here, and it has baked in support for tiled TMX maps as well. The ui framework is awesome, and it has a scene graph and actor style API similar to cocos2d scenes, sprites and actions. The community is awesome, updates are frequent, and the documentation is good. Don't let the java part scare you, it's fast, and you can use jruby or scala or whatever you like. I highly recommend it for 2d or 3d work, it supports both.

I currently use Corona for business applications with great success. As far as games go, I'm under the impression that it doesn't provide the performance that some of the other cross-platform development engines do. It is worth noting that Carlos (founder of Ansca Mobile/Corona SDK) has started another company on a competing engine; Lanica Platino Engine for Appcelerator Titanium. While I haven't worked with this personally, it does look promising. Keep in mind, however, that it comes with a $999/yr price tag.

综上所述，我已经研究了Moai一段时间了(因为我已经熟悉了Lua语法)，它看起来确实很有前途。它可以为多个平台编译，而不限于移动环境，这一点很吸引人。

考虑到游戏制作的复杂性和从中实现的性能，《多媒体融合2》也是一个有价值的竞争者。我想到了Vincere Totus Astrum (http://gamesare.com)。

最近我使用了一个AS3引擎:PushButton(现在已经死了，但它仍然有功能，你可以使用其他东西)来完成这项工作。为了让它在Android和iOS上都能运行，项目在两个平台上都在AIR中编译，并且一切都能正常运行，没有性能损失。因为Flash Builder有点贵(249美元)，你可以使用FlashDevelop(有一些教程可以在AIR中编译)。

Flash可以作为一种选择，因为它非常容易学习。

几天前我找到了一个漂亮整洁的Wave游戏引擎。它使用c#，并具有Windows Phone和Windows Store转换器，这使它成为XNA的一个很好的替代品
