Lueroi has great walkthroughs :) i myself have already beaten the pokemon game series up to the fifth gen. i still enjoy just watching his walkthroughs because i no longer have any of the older pokemon games.
Lueroi's walkthrough series is addictive ;) when i leave school i go home and watch them instead of television. they are full of excitement :D when you think he is just going to go along the routes he changes and he always has an awesome team of pokemon
if you are reading this and do not know who lueroi is you should definately watch his videos on youtube. my favorite is when he nicknames his hitmonlee capt. kick :b also my other favorite is his whole soul silver and sapphire walkthroughs
