But seriously, There is potential with this software. Yes, you need to dedicate yourself to something, (a lot more) to figure it out as compared to other engines that cost lots and almost do everything for you -- But as a starter engine to prepare you for the other engines, this is a good place to start, imo. (and 3dgs is free)
