One great example is 'The Legend of Zelda: The Minish Cap'. It has an engaging story where Link shrinks down to the size of a Minish to save Princess Zelda. The adventure involves exploring a detailed world filled with unique characters and quests.
One that shouldn't be overlooked is 'Advance Wars'. The story might seem simple at first, but as you get into the game, you realize how it ties into the strategic battles. You have different commanders with their own motives and the story of the war between the Orange Star, Blue Moon, and other nations is quite interesting. And of course, 'Pokémon Emerald' has a lovely story with lots of heart, especially when it comes to the bond between the trainer and their Pokémon.
A really good one is 'Pokémon Ruby/Sapphire/Emerald'. The story of becoming a Pokémon master, stopping Team Magma/Aqua from their evil plans, and exploring the Hoenn region is full of charm. There are also the relationships between your Pokémon and the other characters. 'Mario & Luigi: Superstar Saga' is also great. The story of Mario and Luigi going on an adventure to save Princess Peach's voice from the evil Cackletta is hilarious and full of fun gameplay elements related to the story.
The main difference is the story. While the original Fire Red has a more standard Pokémon adventure story, the 'dark story' hack is likely to be darker and more complex. Maybe it has a different ending or a more convoluted plot.
One unique feature could be its dark storyline which might deviate from the original Fire Red plot. It could have different character arcs and more challenging scenarios. For example, the enemies might be tougher or the puzzles more complex.

Pokemon Ruby/Sapphire/Emerald. The Pokemon series always has a good story. In these versions, you start your journey as a Pokemon trainer in the Hoenn region, aiming to become the champion. Along the way, you encounter different Pokemon species, battle against Team Aqua or Team Magma, and uncover secrets about the region's legendaries.
In 'Pokemon Glazed', the story is quite remarkable. It starts with the player in a familiar Pokemon world but soon takes a turn with new threats and a different kind of Pokemon League. There are also elements of an ancient prophecy that ties into the gameplay. You get to explore different areas, meet unique trainers, and face off against powerful foes, all while following this great story arc.
