I just got into the Mostly Walking series a while back and was really excited that you guys played Quest for Glory 1! I watched through that series and saw you didn't really seem to enjoy it, and I can't say I blame you. QFG1 and 2 are REALLY dated, and even their VGA remakes didn't do much to make up for that. That being said, the later games in the series were HUGE improvements on the first two. Specifically Quest for Glory 4: Shadows of Darkness. It may be the best Sierra adventure game ever made next to King's Quest 6 (which I KNOW you loved). It's far more polished, the setting is incredible (imagine a secluded Slavic valley filled with Lovecratian horrors and people who want nothing to do with you), the combat is better, the visuals and sounds are AMAZING, and I just love it. It used to be a buggy mess but recent GOG releases have made it 100% stable and perfectly playable. If you're looking for another game to check out, QFG4 is 100% at the top of my list personally, and I think many of us would love for you guys to give it a shot.
Oh by the way, it's fully voice acted, and it's narrated by John Rhys-Davies (Gimli from LOTR). Have fun!
