If there is one game I'd vote for, it would be the King's Quest 5. Graham is absolutely pitiful in this one, a regular loser. Cedric the gay ass owl was funny too..I felt like shooting the damn bag o feathers.
It was funny seeing Graham fall into a moat, down a staircase, into a dragon's mouth etc in the series.
Also, and APFelon will appreciate this, the plot of KQ 5 has the evil wizard hijacking the entire castle and family, ala Steven Segal or Chuck Norris.
The plot stunk.
