Game-Like Manga wanted

Here's the ones i've read and liked.
1/2 prince
log horizon - it's a novel but it had a manga and anime adaptation.
yureka
also the hack// franchise. never looked for the manga but i've watched the anime.

Thanks for all these recommendations!

You should try The legendary moonlight sculptor, he doesn't get summoned but its still pretty good.

But its a dj which only has two chapters, still it's really good

instead of the fan-made dj why not the actual official manga adaptation? sengoku basara is an old capcom game and as i know it has either manga and/or anime adaptation. haven't looked on it tho.

There's also:
Isekai Maou to Shoukan Shoujo Dorei Majutsu
Tensei Shitara Slime Datta Ken
Doreiku - Boku to 23-nin no Dorei (a game in real life. seinen with sm an lots of psychologigal)
Qishi Huanxiang Ye Manhua
Liar Game (a game in real life. Also has a drama)
Infinity Game
Heart no Kuni No Alice (from an otome game)
Shiro Ari
Battle Royale (another game in real life. Also has a movie)

These I watched the anime, but they have manga:
Btooom!
No Game No Life
Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka?
Overlord
Sword Art Online
Amatsuki
Mondaiji-tachi ga Isekai kara Kuru Sou Desu yo?
Deadman Wonderland (a competition in the "real" world but with powers)
Phi Brain - Kami no Puzzle (not really game, but since there's always a puzzle to solve and I think it was a competiton)
Dragon Drive (he's summoned to the world of the game, but it then becomes more normal, and not game-like)

And those are the ones I remember. I really like manga that are game-like or in a game world ヾ(❀╹◡╹)ﾉ~

almost forgot this one

try the new gate, re:zero, moonlight sculptor and id.

i LOVE 1/2 PRINCE... ヾ(☆▽☆)

Black Haze or Tales of Demons and Gods

This one is from my childhood and it's by clamp, it's called magic knight rayearth, the only problem is they are all girl heroes but the guys looks really yummy and it has a really twisted plot that can make you goes wtf. and yea it's an old manga. http://www.mangago.me/read-manga/magic_knight_rayearth/

Thanks, I'll give it a try.

I love reading the manga "Tensei Shitara Slime Datta Ken" it's one of my favorites as are the anime: Btooom, No Game No Life, Overlord, Amatsuki, and Sword Art Online. I'll have to look into your other suggestions. Thanks so much for your recommendations!

New Gate is cool, I'll look into your other recommendations. Thank you:)

Those are some of the best I've ever read! Two of my favorites!!

Thank you.

Maybe I'll give it a try... and thanks for recommending it to me.

Well it's still really good XD

Battle royale is more of a survival game in an island tho... First japanese live movie in vhs i've watched in the 90s. Only thing about it is it's gory so heads up on that.

Amatsuki is a personal favourite. I idolize the mangaka since day 1. Phenomenal art. Forgot to include that. It's not a game but the boy was transported to a parallel universe. Loveit.
