Hero's Quest and Quest for Glory 1 EGA are the same thing, so I'm not doing them separately.
Quest for Glory 1 EGA -
Best: terrific idea, great characters, good story, no ticking clock (except when getting the root for Baba Yaga)
Worst: training your lockpicking skill enough to make money as a thief
Quest for Glory 1 VGA -
Best: same, except better graphics (except when you come into the garden scene)
Worst: combat screens are worse
Quest for Glory 2 -
Best: terrific ideas, love the Arabic setting (yes, even Keapon Laffin ... and even the maze-o-streets)
Worst: having nothing to do in Raseir until night falls ... so you walk around the fountain. Around ... and around ... and around ...
Quest for Glory 3 -
Best: great setting, love the liontaurs and leopardmen village
Worst: training up your skills, various crash-to-DOS errors (and this was solved in the Steam/GOG release, which shows how old I am
), and ... ugh ... "Why did you come here, Friend of Rakeesh?" draining your honour score, which sucks if you're a paladin
Quest for Glory 4 -
Best: LOVE LOVE LOVE the setting, terrific music and music, wonderful voice-acting
Worst: the infamous Error 52 (and this was solved in the Steam/GOG release, which shows how old I am)
Quest for Glory 5 -
Best: terrific music and setting, meeting all your old pals again (yay, Rakeesh!) and seeing what they've done while you've been away
Worst: the story is kind of meh; QuickTime error means you can't finish the game (and this was solved in the Steam/GOG release, which shows how old I am)
