Cons
Con Not moddable
Con No tutorials, forums are "strange."
Con Not an actual engine
Con Not frequently updated
Although it's got very nice features as is, and the team does respond to issues at a pretty good rate, the engine itself takes a little while to get updates. It's a 3-4 person team, and they need to work jobs on the side in order to bring in income.
Even though the updates come out a little slower than other engines, the team is still very much committed to the project and still support it well.
