Anime similar to "Overlord" (The mores episodes the better to)

I don't really know how to mark spoilers properly so anything that I see that could be considered a spoiler I was right "SPOILER" right before it. (Either before the sentence or literally right before it)

.

Hi there, I watched Overlord and absolutely loved it. I was hoping someone could suggest something like it. I'll list the aspects that I liked about it so hopefully that will help. I will also list what I have seen that could be considered similar to it.

• I enjoyed the fact that he wasn't alone, that he had companions (Even though they were just servants... Honestly, I prefered that they were servants)

• One of my favorite parts about this anime is the way the characters goes about everything, instead of charging right in he makes sure he has more then adequate information and then forms some sort of plan.

• I liked that the MC was working for somewhat of a good cause but he was using any means necessary to achieve it (Even if it really wasn't a big aspect in the story I liked that he was trying to help any other players from the game (SPOILER?? Even if they don't come across any other players))

• I really love main characters like this who could be considered scary, (Put yourself in the shoes of the people who stand in there way type scary, not actually scary for the viewer) because it just added this awesomeness to the show (I really can't explain, I am sure that you at least understand what I mean though... Kinda like SPOILER?? Alpha Stigma bearers in TL of TLH, particularly Ryner Lute... (The MC for those who don't know))

Alright, time for shows that I would consider similar to what I said...

• Well SAO is almost nothing like it other then both involve people being trapped in a game I am putting it becuase I have seen similar threads but they were all plagued by almost the exact same set of responses

• Log Horizon, I haven't actually watched this one but I have seen the first episode and really didn't enjoy it. Putting it here for the same reason has SAO.

• GATE, I guess this could kinda fit so I am putting it here. (Am currently watching, and enjoying.)

• Problem Children Are Coming From Another World. Well this one doesn't deal with people being trapped in a game or anything like that it does involve people coming from a different world so... Yeah... Didn't enjoy this one. (Similar situation to Log Horizon, watched a few episodes, didn't like, just don't want to have it pop up in here.)

• I have also seen people say Code Geass so... Please, no Code Geass...

Ahh I can't think of anything else, if I see someone post something that I have watched I will just add it to the list, thank you for your time and responses.
