Hey all. I have gotten myself into a slight problem and I'm hoping you guys can help me out. I am trying to become a budding game programmer and have recently gotten serious about trying to development a game for my portfolio. After moving to Macs from Linux and Windows last year, I have become very comfortable working in OS X. I like XCode and would prefer to use it for any and all coding I do. My problem is that I can't seem to find many game development tools that work in OS X. They all seem to be Windows only. I have only found two "tools" that are Mac compatible: Unity (http://unity3d.com/unity/) and Torque (http://www.garagegames.com/products/torque-2D). Sadly these cost a fair amount of money and, as this is a pet project, I am not ready to sink $200+ into a piece of software I may not us often. Basically, does anyone here know of a game development "toolkit" or engine that is compatible with XCode and OSX? I have experience with Microsoft's XNA Toolkit, but would rather not have to force my development to Windows if I don't have to. Cheap (or free) would be nice, but I'll take any recommendations you guys can give me. Thanks ahead of time for any information you guys can give me.
