well duh, all of the merchandise and movies that spawned from it is a clear fact of that, but video game wise? come on, name one rider/toku game today that people cared not because it has those characters in it, but because its actually good game that anyone can enjoy, none comes to mind because every single one is a piece of mediocrity or sometimes, even worse
and it's not because they can't make one, its because they don't want to, take climax heroes for example, its made by eighting, of all people, which has made several decent fighters in their portfolio, that didn't stop CH from being a very mediocre fighting game with very simplistic mechanics, its not because they're incompetent, but because of the limited budget, resources, and the fact that bamco wanted it to be that way
if bandai thinks that the tokusatsu genre is important enough, obviously they would've cared to make a game with higher qualities that what we've gotten so far, they have no need to ask for KT just to make a decent musoulike, saint seiya is a proof of that, it's non KT game, but has a decent gameplay built in it, and it even manages to spawn an overseas release to boot, ranger cross doesn't have any one of those despite having a great potential to be a good musoulike.
my point is, i love tokusatsu, Japan loves it, all of you loves it, but game-wise, it will probably never be taken seriously by the ones who made the games.
