10 games that are really hard to beat

What are the hardest games to beat? IGN takes a stab at the question with a listicle of 10 doozies. Devil May Cry 3, Battletoads, MDK2 (awesome game), F-Zero GX, and Mega Man (take your pick) all grace the list. But the crown goes to non other than good 'ole Contra sans the Konami code, of course. If these were the only games to feature Achievement Points, you'd be broke.
