My name is Kyle Finlay (also known on the Unity forums as Sir.Tiddlesworth). I am a student and a aspiring game developer.
I have been using Unity for about three years now (since version 2.6). Before I discovered Unity, I used Game Maker, Klick & Play, and FPS Creator. I have also tried various other engines such as Shiva, UDK, Cryengine, Dark Basic, Blitz Max etc. But none of them come close to Unity in my opinion,
