Hi guys, just deciding if i should get unity or not as im going to learn to make games but i needed to know if i use Unity free, can i sell games online? And also what are the benefits of pro over free?
Yes, you can sell games with free versions.
Pro have many benefits, but basic ones - there is real time shadows, no Unity logo at startup. Generally basic Unity usable for most of the projects. While Shiva3d don’t have LOD in free version - so getting good looking graphic is nearly impossible in free Shiva in 3d worlds.
Cool, thanks alot for the quick reply. 
the free edition of shiva doesn’t allow you to export the project.
it’s for testing purposes only. (try before you buy)
