That is impressive... way to go!!! Was it hard to attune your editor skills and learn Unity?
Thank you! I actually didn't learn Unity (see below).
Quote from Zolden: Go
But there's another way. One can only bring his game design skills to the new engine. In sc2 we had a great possibility to receive almost immediate feedback from the players across battlenet and gain better vision of what players like to play and what is boring. So, if someone thinks his game idea has proven to be popular as sc2 map, he can hire coders and artists and implement his game in unity as a game designer and team leader. I think it's what Karawasa did.
That is exactly what I did except instead of hiring people I asked them to join in as partners. The history of the map (don't forget WC3) helped tremendously.
