>>27209542hey, man, he's entitled to his opinion. It's cool, really.
>>27209520as mentioned, a spritebased fan ROM with these environmental variants shouldn't be too much harder than a normal pokemon or just RPGmaker game as I might be able to tell.
It's just having the sprite assets, tying the different appearances to basically the same code blocks, then making sure those variants appear only either in the hands of trainers, in their proper environs, and stay that way than fluxing constantly.
But, again, I'm not a programmer so I can't say with certainty.
