Played this because I saw a post on Reddit describing FireRed Omega as the OP's favorite game of all time, and uhhhh I don't get it!

See, I have a weird relationship with Romhacks. On the one hand, this feels like an improvement on FireRed in a lot of ways, and it's great to have a much wider variety of Pokémon in Kanto. On the other, something about the fan-tweaked nature of the game feels hollow and inauthentic. It was cool having a Tyranitar before my 5th badge, but does it really change the game in meaningful enough ways that I'd prefer it over the original? It makes it possible to collect the whole National Dex in one playthrough without trades, but for whatever reason, the artificiality of this release prevents me from caring.

It feels like it changed too little to be worthy of praise. Pokémon Romhacks are better when they introduce recent generations of Pokemon which didn't exist at the time of the original release, or make their own new region from scratch. This was a fine time-waster on my phone, and ultimately still a solid Pokémon game, but I wouldn't go out of my way to recommend it to anyone.
