I start playing Vassal modules some time ago. There are so many great Vassal Modules out there for wargames. But you hardly find any non wargames. I started to create Vassal modules for those games. I hope this helps to increase the popularity of Vassal engine outside of the wargaming world.
I really think Vassal is much superior than tts or tabletopia.
If you find any bugs, issues or you are missing any features in my Vassal Modules please let me know.
