I like dungeon. GBA themed, they're just so easy!

I can't really pick one theme.  I like some monsters from all of them.

Well, choose the onwe that has the most you like, or the one that fits your style of fighting, like how I thought you like fire. Other also fits you, too.

I chose other, because I love fighting Darknuts, Ball & chaimn soldiers etc. They don't require awkward methods of killing, but are a fun challenge to your basic skills.

Yeah, they are very good challenges. Of course, though, the toughest GBA one from other are Lynels, they are pretty much the toughest none boss/mini-boss monster in the Oracles.

I like the bosses, Ganondorf especially, and the Darknuts and Bokoblins.

Boss battled rock, but Twilight Princess has blown the other games out of the water in terms of Boss Battles!
