Siege is what I'd call a competitive puzzle/action game. Much like a puzzle game, it involved joining up a few blocks to create something. Join up two iron blocks and you get a simple footman. The larger your block combos, the more powerful your creations get. You could create airships, dragons, and necromancers with much bigger block combinations.
What makes it better than most puzzle games is that you could play it against a friend. There's a few strategic choices.. you could go with a simple, tough castle, or a fragile fort that lets you build the more advanced units. Unit choices can be interesting too, send forward armies of small troops or mix between soldiers and archers. Or you could spend twice as long to build an army of knights.
Graphics and music are simple, catchy, though there's quite a bit of excess blood and gore.
The drawback is that single player is not much fun, only worth it for practice, but it's a quick, light game, fun for multiplayer.
