The Pokémon games have changed a lot since the series debuted 25 years ago. Combat is an area that has seen a particularly big change, with perhaps the biggest being the addition of Mega Evolutions in Pokémon X and Y. When exposed to Mega Stones, some Pokémon may become enhanced versions of themselves that boast special attacks. and attributes. The feature was absent in Pokémon Sword and Shield, but its inclusion in the Let's Go games - remake of the first pair of Pokémon titles - seemed to lend credence to the idea that Mega Evolutions could return in Pokémon Brilliant Diamond and Brilliant Pearl. . Unfortunately, that's not the case.
There are no Mega Stones within the games, which means that Mega Evolutions, once again, haven't been cut, so don't expect to see Mega Evolutions from any of the Sinnoh Region starters. Combat in the remakes is pretty much the same as it was in the original titles, albeit with much prettier graphics.
While Let's Go games were essentially improved remakes of the first generation games packed with new features, Brilliant Diamond and Shining Pearl are more like enhanced ports; there isn't much here that didn't exist before, at least mechanically. While the foundation upon which the remakes have been built is quite solid, unfortunately, it also means that it also lacks many of the features that Pokémon have introduced since the original Diamond and Pearl came out.
