Five Stars for the amount of quality content included in the bundle. I've reviewed or played each adventure individually and they range from 'pretty good' to 'amazing.'
My personal ranking of each included adventure from strongest to weakest:
Struggle in Three-Horn Valley - Fun lost island adventure with lots of interesting content and a good mix of story-telling and exploration.
The Haunt - Excellent and suitably creepy haunted house one-shot dungeon.
Minotaur's Betrayal - Features fun minotaur allies and villains and a truly massive orc stronghold dungeon.
Mini-Dungeons #1 Caves - Collection of three dungeons; the first is included in Struggle in Three Horn Valley but the others are nice, drop-in mini-dungeons with some neat features and lovely maps designs.
The Amulet of Shavaka - An entirely self-contained, mid-size undead dungeon. Light on story and heavy on combat.
Something Smells Fishy - Interesting but short murder mystery around a fishing town.
Minotaur's Bargain - A small arena dungeon filled with traps that doesn't do much with the minotaurs themselves.
You can find my written and video reviews (and in the case of The Haunt, our actual play session) on my website and YouTube channel.
