I see it similar to AlbertoT. It would be great to have a good competitor. And in terms of workflow GameCore is really great. It is sad to read that they gave up on this.

I also understand that they never made enough money from it. The presentation and marketing was just bad, images and demo games were not impressive enough. It could not survive this way. Actually they were in need of at least 2 more people, one responsible for marketing and support and another one creating art, websites and demo content. I think a team of 4 people could make it: engine programmer, tools programmer, artist and marketing guy. There are still tasks like documentation that have to be done by all of them, programmers can write programming and scripting parts while the artist and marketing guy can help with tools and workflow docs.
