barring the effects that time might have had on Kanto; where you see that as a problem, I see that as one of if not the only real appeal of the idea
Don't understand me wrong, I think IF Kanto was to return (which I don't think it should) it definitely should change a lot, but I suspect that would upset a lot of people who want to go back to Kanto.
he same could be said of why people might want remakes
I'm not a fan of the remakes in general. I'm mildly interested in Sinnoh remakes because I have never played a Sinnoh game, and even so I'd only buy it if they'd include new Sinnohan forms. Kantonian forms are much, much less likely than Sinnohan forms.
