I know you've mentioned manga, but each of the items listed are all animes as well, so is that what you mean to be referring to? ._.

If so, I've seen quite a few as well. As mentioned above, Full Metal Alchemist is a fantastic place to start if you're interesting in finding a new show. Also, I've heard raving reviews for Sword Art Online, though having not seen it yet it's not something I can entirely vouch for.
