company that decided to share part of their software for free and allowed people to commercialize their creations as "greedy".
It is hardly free. Even the "free" version needs to be activated online with their servers. Think of it more as an unspecified time limited demo.
Again they only release this version in the hope that it (for some god forsaken reason) would get into education syllabuses or university where they can trap potential game developers within their mitts forever. Luckily they are currently failing to achieve this ;)
