Playing a dragon and doing what dragons do best (kidnapping princesses, burning villages and farms, and taking all the gold you can) is a blast. I've had a lot of fun and a lot of laughs playing this game. It is overall simple, yet it contains some complex elements. You can destroy towns and farms regularly or you can leave them alone and let them prosper, making farmer carts and wagons more valuable. You could even choose to make a town fear you and send you tribute instead of destroying it, but enemy dragons could destroy it or even make a town fear them instead. You can upgrade your dragon to suit the situation. The dragons change visually depending on how they're upgraded, which I thought was a nice touch.
Hoard is at its best when you have friends to play it with. I still have fun in single-player, but the AI is not a challenge and has not been polished. I can easily end a round with more than 200,000 treasure while the enemy computer-controlled dragon has about 1,000 treasure. The AI is prone to flying straight through enemies without trying to dodge. Computer-controlled dragons will also sit on top of powerups for long periods of time in an attempt to pick them up, yet they can't because they already have a powerup that's ready to use. I've also had problems with computer-controlled dragons just hovering in random places for very long periods of time, causing them to get killed. You can play with up to four friends, but if you don't have enough players, the game will fill in any extra spots with computer-controlled dragons.
I don't like the game's current music. It is too serious and doesn't match the fun, light-hearted nature of the game. I would recommend downloading and installing the old music. It really improves the game's atmosphere.
I think the game is a bit pricey, but I'd recommend getting it and the DLC when it goes on sale. Definitely try to get friends to play it with if you get this game.
