You listed a bunch of shows that you liked, but what exactly did you like about them?

Recommending against No Game No Life. It's great, but it's full of fanservice aimed toward the the most dedicated of deeply entrenched anime fans; certainly not starter friendly. The story is unfinished, as there's about 6 volumes that haven't been adapted, assuming they get adapted at all. I very highly doubt that it will, considering some of the notoriety/controversy surrounding the author. 12 episodes.

Elfen Lied is violence for the sake of violence. There is a plot, but its claim to fame is the extreme gore (and it should surprise no one, you've seen worse in real movies). I'd only tell you to watch it so people will stop trying to recommend it to you. 12 episodes.

While Bleach is complete (technically), it's a long standing series akin to DBZ and Pokemon. If you want more "shounen" demographic shows to watch, go ahead. There's a couple of guides out there that detail which episodes are purely filler, so you can skip them if you please. 366 episodes + movies.

Steins;Gate is a slice-of-life/mystery/time travel show, and it's great for people who want a lot of genres and ideas put together for someone to figure out what they want from future shows. I think it sucks, but other people are free to disagree. 24 episodes + movie, "season 2" is incoming.

Clannad (CLANNAIDS) and Clannad: After Story is probably the most solid watch out of all of those shows you listed. It's a little formulaic, but it's one of the few shows that has the formula correct: equal parts comedy, drama, strong characters, and a plot. 47 episodes, 2 alternate route episodes; don't watch the movie.

But really, I'd recommend Boku no Pico. 3 episodes full of excellence. ( ͡° ͜ʖ ͡°)
