>>42924240The Lufia overworld sprites are just about on par with Pokemon, so it's less that the graphics too good for Pokémon, and more how we're so used to Gen I and II's looks that we've conditioned ourselves that that's the standard we should keep using even though we can do much better without necessarily breaking the style of the Pokemon universe.
Also, if you're doing a Gen II hack with largely no upgrades to the overworld maps, then you're not really taking advantage of the new strides of improvements that the disassembly have opened up.
