OK, wasn't really good, the later HP GBA games (Goblet of Fire) was better, tho it was better than Sorcerer's Stone.

Bad Graphics, decent gameplay, I perferred the GBC and PS2 versions.THe difficulty was kind of in the middle.i wouldn't buy it full price, I'd get it used, or just rent it. Or, go with the GBC game, though it's more of an pokemon-like rpg. Or if you want a game along the same lines as the GBA game ( and you have a PS2) you might want to get the PS2 version fo the game.It's not going to take very long to beat, and unlike the GBC version, you can't play agin and do additional things, mini-games and side-quests.You'll probably play it for around 12 hours, whereas the GBC game u could play for more than 50 hours, and the PS2 around 30.
