The worst game you've ever played

[Zac]

I've played some really awful old NES games, and a ton of early PS1 and N64 games that are completely devoid of any kind of appeal, but I think the worst games I've played are some of the mindless, monotonous and boring hack n' slash games that some people seem to like.
Some hold my attention with good characters and intresting narratives, but I can't say the same for games like the Force Unleashed 2...
