Log Horizon is a good one

I could not agree more with this statement. If you liked Light and Lelouch then you'll almost certainly like Shiroe as well.

Steins;Gate is also good
Black Lagoon is amazing
C the money of souls and possibility control

Agreed.

I'd like to suggest Guilty Crown as well. If you enjoyed Geass then there's a good chance you'll like it, since they basically copied and only slightly altered Geass' plot when they made it. Personally, I hate that show, since every single second of it I watched did nothing but remind me of how much better Code Geass was, but its been given some surprisingly good reviews, so some other people clearly do enjoy it.

Also:
- Jormungand
- Darker than Black
- Shiki
- Basilisk
- Baccano
- Un-Go
- Devil Survivor 2 (there isn't a first one; it's based off a game, like the Persona 4 anime)
- Towa no Quon

I'd advise all of those above, but especially Baccano. It's plot doesn't sound all that great on paper, but it really is one of the best animes I've ever seen.
