Servicable and inoffensive remake, but missing almost all of the mechanical and aesthetic peculiarities that make gen 1 interesting, like the chiptune music, the low-fi bichromatic GBC colorized visuals, the primordial off-model monster designs, and most importantly, the terrifying pantheon of the imagination that is glitch Pokemon and glitch interactions
I'd take Glitch City over the Sevii Islands any day, the most important part of gen 1 is the unauthorized feats of alchemy, Missingno multiplying your items, obtaining Mew to finish your dex by leaving a specific trainer alive and going on a fetch-quest, getting your game frozen by an infinitely screaming interdimensional creature with a gender marker for a name, stuff like that
FR/LG is missing all the cool stuff
