You think so? I would hesitate to call M-Size products "games". They're digital CYOA novels. There really isn't much game to them.
ToT, and others like it, at least have some element of gameplay. That aspect alone, in my opinion, makes them better games. We can debate the content and which better exemplifies femdom, but a VN being "miles ahead" of an RPGM product as a game seems to be a self-contradicting argument.
Maybe this is my bias speaking, but I'd much rather play ToT, flaws and all, than any M-Size VN simply because ToT is a game, not a novel with choices. M-Size does great work, but I feel it's a stretch to call those products games.
Unless M-Size has a body of work I am not familiar with, in which case I'll stand corrected. What I've seen though clearly fits into the VN classification to a T.
