Approved. Here are some good and bad aspects...
[+]What most reinforces this campaign: custom spells.
[+]The story is something between a drama and a comedy, the introduction was fun.
[+]A mix of Blizzard's sub-maps with Return of the Dragon's cave-walking.
[?]Grammatical mistakes. This doesn't affect the gameplay though. What is with people and "Elfs" anyway?
[+/-]Somewhat original storyline, inside the Warcraft lore. However, the story could have been different and a bit more interesting. A Tauren who is interested in mechanics, that part was the most original in my opinion. But Furbolgs? :\ (I'm not asking you to change this by the way)
[+/-]Terrain is OK, the roads are good, however, the parts outside it could use some work. Right now it looks too plain, especially outside the roads where there's little to no elevation.
[-]Heroes take food, usually Campaign heroes do not take food. In the Tauren mission, we could hire some extra warriors with that food.
[-]The missions themselves are usually boring and bring little or nothing new to the game.
[-]The Earth Mother mission takes too long to be completed, I didn't finish the campaign because when I drew attention to the defenses, Neparne died. Guess what? 12 seconds left for the Rampage to end. Going through it all again? No way.
A 25 or 20 minute resistance would be perfect in my opinion.
[-]Some items are a bit imbalanced. You spend the entire game searching for useful items only to find charged items, and after you defeat a boss you get a wand that boosts your stats, your life regeneration, your mana, etc. There could be more permanent items and less strong campaign items.
[-]The most awful in Hoof of Honor: the music. Not only loops of pursuit themes and other campaign-music are annoying, as the music chosen just doesn't fit. And the worst is that they are sounds, so even if you disable it, the music won't stop.
About disabling sounds and enabling music, sorry, no, I personally like to know I'm in Warcraft.
My rating for this resource is 3/5 (Useful). Spells certainly are good, but they don't make up a campaign.
