Pokémon psychic is a(n) interesting hack, which is rare among hacks that are revolved around legendary Pokémon, especially in this hack "psychic" legendary Pokémon. The starters are legendary but no matter which one you choice all three are available later on in the game. Your rivals Pokémon team is still unchanged, it would be the same  team as one you would see in regular sapphire.
Graphics: I gave a 10 because they are good, average for any Game Boy Advanced platform game.
Sound: I gave a 10 because it was good quality sounding with no irregularity's, but its the exact same sound heard in  the game its based off of which is Pokémon sapphire.
Addictiveness: I gave a 5 because the game wasn't very fun from a "whole new adventure" point of view, but what did make it slightly more enjoyable was you could obtain/capture what would other wise be event Pokémon, so that gives it a little replay value.
Story: I gave a 5 because its the exact same,word for word story of Pokémon sapphire just with different Pokémon in the wild.
Depth: I gave it a 5 because the game has basically nothing to do after you beat the elite 4, it is a relatively easy and quick hack to beat estimated time for beating the hack is about 8-9 hours or less, but this is mainly because of the legends in the game, there stats are already high and are naturally stronger than normal Pokémon.
Difficulty: I gave a 3 because  the hack is the same layout as sapphire(landscape wise), so navigating through it is fairly easy and not much of a challenge, with the legends easily catch able it didn't add to its difficulty ,( plus there naturally higher stats the game), made it  basically a cake walk, Pokémon trainers and gym leaders Pokémon and Pokémon teams were unchanged thus making winning easy.
I recommend this hack for anyone who enjoys legendary Pokémon, that could only normally be obtained threw a special event, and if you want a easy steady going hack to beat.

Nice review here. You improved on the previous ones by giving more depth and detail. Love that it's easy for anyone to understand, even the less experienced pokémon players. You broke it down and explained why you said what you said. Very nice.
