Alright my memory is kinda vague about this manga, from what i recall it was about some a guy in a MMORPG or something alike where ur consciousness enters the game i think and suddenly the game closes and the players inside cant exit and if they get unplugged outside they die and if they die inside they are permanently dead mass panic ensued inside the game and some players suggest travelling together the main char thought it was a bad idea, if i recall right the players needed to beat a dungeon or tower to get out.

As i said my memory about this manga is kinda vague, already checked catagory under Game/mmorpg and alike seems like i didnt put it under Reading or wish list and checked several familliar links but cant find it.
When i last read this there was only one chapter this is the most i can remember about it, some parts may be wrong or im just recalling a wrong scene

SWORD ART ONLINE!!!! WOOOHOOOOOOO!!!!!

lol i just found it out myself, funny how things work after searching i post and after post i check abit more and after i check abit more i find it and then someone already posted ^^

I think it is best to read the Light Novel though. Baka-tsuki has translated it to quite far. English versions of the manga are very little actually

thanks for the recommendation ^_^
