there is only one reason why i might switch to unity sooner or later and thats rather simple, LEVEL LIGHTING, blocks are so out of date and the radiosity takes decades to generate, i went to bed leaving ma pc on, radiosity on minimum setting and when i woke up, about 62% wat tha!! come on, i love everything else about GS, but damn man, its like they dont expect us to make more than a room size demo, or to use some external app... so, i may be visiting unity to see if they do better level lights
