Please recommend me gaming type anime like .Hack// and No Game No Life and other gaming Anime.

There are two that come to mind. The first is Ragnarok: The Animation. It's based of an online MMORPG and uses gaming terms within the anime. That's all I know, as I haven't actually seen it myself. I don't know if you'll like it o not, but tu should give it a shot.
The segundo it Btooom!!, an anime that doesn't actually take place in the game, but has a plot surrounding it. Without too many spoilers, something similar to SAO happens in which a new game comes out which everyone loves, but certain people wake up and find themselves in a real-life version with somewhat of a twist. This one I have seen and absolutely loved.
I don't believe Btooom!! has a game out but Ragnarok and Ragnarok II are still available online I believe.

-There's one that came out last año I think.. and it's called Log Horizon.

-There's an even newer one called Overlord. Personally I haven't watched it but I've seen it around.

-Accel World is an online game type anime as well I believe.

That's about it for ones I've seen.
