My list (In no specific order):-
1) Harry Potter (First 3 Installments & Half-Blood Prince, rest of them are not difficult, but frustrating!)
2) FIFA (All)
3) EA Sports Cricket (04 and 07)
4) NFS Underground 2
5) WWE Smackdown - Here Comes The Pain
This was for the easiest games, now for the hardest games: Link

The Ghostrider for PS2 is easy too, I beat it in about 2 hrs.

2. All Spyro games in general
Thats pretty much it, or maybe its just me. I probably have too much time.
