Because Windows 7 is no longer going to be supported at all next year, I'm planning on fully switching over to a Linux distro instead of upgrading to Windows 10. Currently, I've been experimenting with openSUSE, but I still don't have a development environment set up for it. Are there any good utilities or engines I'm overlooking while I make the transition? Most of the art and audio programs I use are FOSS (GIMP, Krita, Audacity), so that won't be much of an issue when transitioning.

On Windows 7, I currently use Visual Studio as my IDE for C# programming on Unity. How is the Linux build of Unity nowadays? I'm alright also alright with not using an IDE and just having a text editor.
