The most difficult part of reviewing a game is reviewing the difficulty. A few games—Super Meat Boy, I Wanna be the Guy—can uncontroversially be called hard, but the essential question is actually whether they are too hard. Since that level of difficulty depends not only on the individual player's skills and experience, but also on his values, it can be difficult to state what goes over the line. It is even harder to accurately say whether a game is too easy, primarily because most reviewers are skilled and experienced gamers, many of them drawn to the hobby during its early days when challenge was practically all a game could offer in terms of fun.
