How did I forget Pluto? <slaps head> It's basically a master-class in how to de-construct and then reconstruct a dead horse into something quite beautiful.
I haven't read that one, actually, it's like a re-telling of a classic manga, yes? I also forgot to mention Master Keaton, which is some fun globe-trotting, mystery-solving mayhem, and you even learn a bit about history from it, too!
Another entertaining one I've gotten into is Jin, which is about a doctor who gets sent back in time to the Meiji period of Japan. He takes up his practice in Edo, and has to improvise a lot of his materials, medications, and such in order to treat patients using modern techniques. The science behind a lot of his surgery techniques seem pretty well-researched, and the scenery in it is simply amazing. You really feel like you're walking around in ancient Japan looking at some of the pictures.
If you enjoy the humorous parts of ToG (I sure do!) then you might like The Devil King Is Bored. Only about 20 or so chapters are translated, but it's really funny. There are a lot of references to RPGs like Dragon Quest and even some Monty Python in there too.
"Be Mine, Hero!" "I Refuse!" is another fantasy manga I've been into. There's a lot of stuff about economics and politics in it,some humor, a bit of action, and the Demon Queen will be your number one waifu after you read it.
However, for the TRUE Tower of God experience, get yourself a Gameboy emulator (the oldschool black n white one) and a copy of Final Fantasy Legend (Makai Toushi Saga). I suspect that SIU has played that game, and it was the first thing I thought of when I started reading ToG. It's an RPG that takes place inside of a tower, with multiple races in your party, where each floor is the size of a continent, and there are conspiracies at work with the higher-ups. Its a fun little game if you like RPGs, and the sequels (which retain the same flavor) got some very pretty DS remakes with fan translations. Each one is a great way to kill 20 or 30 hours while you're waiting for SIU to work his magic once more.
