A VTT isn't a game by itself, it's literally a virtual tabletop to play other games such as D&D, a computer version of a physical tabletop with miniatures and such. Project Sigil was meant to be Hasbro tossing their hats into the ring, and almost certainly why they tried to kill the OGL(there's a whole thread on this elsewhere on the 'spark) as a lot of the provisions would have blocked any other company from duplicating some of its features. With that not happening, they had to actually compete, but couldn't cut it apparently. The guy who had been running it was originally from Zynga, a company well-known for microtransaction-stuffed mobile games, and undoubtedly had planned to stuff it full of them.
