That info is in the "More Details" section. With that said, do you still think it should go in the main table? Was trying to keep it from being too cluttered.
It might be good to include brief license information in the cost column -- for example: "free (MIT)". There's probably at least vertical space in the column for that along with a price, and it's conceptually related, particularly for licenses that carry responsibilties with them.
I can't speak on behalf of everyone, but the license it's under is a deciding factor for me when looking at engines and libraries. It's definitely something I'd love to see at a first glance.
