I loved all of the Quest for Glory games, but Quest for Glory IV was easily my favorite. I re-installed it recently due to that great sale at GOG.Com, and so I'm once again making my way through Moravia.
This game was great not only because it was one of Jennifer Hale's first video game voice-over performances; it's great because the music is unabashedly cheesy and joyful.
The menu music is a real standout, particularly the super epic, wailing keyboard guitar solo that starts at 1:19. Best of all, on my PC, for some reason the audio coding got weird, so that entire solo was about fifteen cents sharp or something. So it was painfully out of tune, and even more epic and hilarious.
Go ahead, keyboard guitar soloist. Show us your best guitargasm face.
