These are my thoughts as well, and if true I want names, years, and platforms!
It'd be cool to see what all they could do with Blitzball with modern technology, though I can't say they're missing out on a game money maker with it. I know X has its fanbase, but I don't think it's larger than say, VII. Though none of them are as large as VII's. And if they tried too hard to compete with the likes of FIFA then I don't think it'd go very well.
But smurf, I'd be game. Especially if I got to play as Yuna again.
