Pokemon unbound

It’s by far the best most detailed rom hack out there. You don’t find another one that has anywhere near the features that unbound does with an entirely new custom region and story with all of the QOL features and gen 1-8 Pokémon

There are games like radical red that have all the same features but are just upgrades of the original games. Unbound has that and is an entirely new game. No other rom hack comes close. It’s better than most fan games

Pokémon odyssey has a slightly better art style and offers custom Pokémon or nintendo odyssey monsters however they don't allow anything sinnoh or higher besides ev mons which is why this game is only a polished style modernized gba hack. Odyssey and unbound are definitely the top 2
