I'm never fond the 5th generation map to be too confusing, I've memorized every place and can make my way there with ease...
First you said fond, then you said 5th. If you know what the 5th gen map looks like, post a link please.
Anyway, the fourth generation map is really easy. The third generation map I never really understood. Whoever said they wanted to burn a tentacool doll, I am with you on that.
Well, I know how to beat the third generation games without getting frustrated FOR A LONG PERIOD of time. Here is the procedure:
Get to the part where you have to surf from Lilycove to finish the rest of the game (Slateport, Pacifidlog, Mossdeep, and EverGrande)
Save the game
Go out and buy a tentacool doll
Finish the parts that require Surf, Dive, and Waterfall
Burn the Tentacool doll
Finish the rest of the game.
Anyway, I have the 4th generation map layout all figured out, it was not really hard... at all... Guess certain people have different areas of expertise.
