Providing work does not call me I plan on participating for the first time here.
I have recently picked up Unity 3D and am working on a title with a partner but this will be a quick solo weekend to see how far I can push my Unity skills as that will benefit me overall and have fun while participating in the challenge.
For art I’ll be using Adobe Photoshop , Adobe Illustrator, and my personal library of photos / source textures.
For models (if used) ill be using Silo 3D and Blender 3D
For sound I’ll be engineering on my iPad with several different sound apps as well as possibly Fruity Loops on my PC. I may also dip in to sfxr depending on what the theme is and my game ends up being.
For personal code libraries I have some button pressing code that I re-use for projects but otherwise I’m new to Unity so there wont be anything else to bring over. I’ll probably stick with Monodevelop although if things get rough I could break out VS 2010 profesional ; trying to get away from it though 
Its unclear if Unity plugins are allowed like 2D Toolkit, PlayMaker etc? I’m going to assume so because they are not actually game code? If not someone drop me a line so I can avoid them? I don’t know either very well anyways so it wont be a tragedy to not use them but I don’t want to get disqualified if I use them and its a ‘no-no’!
The fastest game I ever made was about 3 weeks .. Leprechaun’s Luck for iOS/Android heres a screenshot so you don’t get bored at the wall of text:
