Cons
Con Incredibly Expensive
$99/mo for full functionality probably makes this the least accessible piece of game development software in regards to price, all with a very limiting feature set.
Con You are restricted by it's limitations
For example, you can only make certain kind of games.
Con Not very powerful
You will be limited to using templates to build games.
Con Subscription Model
The two more reasonable price points limit the functionality of a software already far less powerful than many more cost effective alternatives.

Con Very expensive
Buildbox has a 15-day trial version, after that a $2675 license to use it must be bought.
Con Stability Issues
The software has stability issues on Windows, with the preview window causing program crashes when simple functionality is added.
Con Slow
Everything takes ages..feels like Unreal 4
Con Lack of user-interface
Although you can customize a lot, the user-interface does not show that. But plans are in place to improve this with some front facing GUI into the LUA scripts so you don't need to code as much.
