No, I wouldn't say it is. The files are good, they work, that's not the problem. The problem is the lack of customer service. You can't contact anyone if something not working and it's not part of the base server file. A friend of mine was trying to put in the sash system, doing everything well as it was in the tutorial but the game cannot compile. He wrote to TMP4 but he only got the answer to ask his question publicly otherwise he doesn’t help him because "private help doesn’t help the community". (WTF?!) So if you stuck with an error, you won’t get private help from him. Obviously, you can't ask every question in public for several reasons, and what a lame to ask everything in public anyway...
I only recommend using this release if you are not a beginner or already have a developer on your team. Otherwise look for another release where there is a customer support, because believe me, you need it especially as a beginner.
