Quite a good game with surprisingly great graphics compared to the most recent generation. Gen III has obviously taken the cake for most improved graphics. It is not the best, but that's justifiable being as it was only 2004 when the game was released.
The sound is typical, but still solid, it could be better, but still solid. It is the epitome of sticking with what worked, and it does work.
I always play this game, it's super fun and I absolutely cannot stop, it is really fun battling and trying to be the very best, like no one ever was.
The story's a bit patchy at first, but the further you go into the game the more personal relationships become and the more you begin to understand the story.
It is really in depth and this time you actually have a dad for once, this brings about a new depth and a bit more of a back story for your character along with giving them a goal or motivation on a family level.
It can be difficult quite a bit of times, especially once you beat Flannery, it becomes a bit harder, but still relatively easy. There are actually 2 gyms in which you might have to be like 5 levels ahead of all their Pokémon and have them know at least one move their Pokémon are weak to and you'll need an endless supply of potions and revives, but again relatively easy.
