The first online game I played was Evony.  It was fun but I got bored since with a war game like that it's hard to do anything else since you have to keep an eye on your cities all the time. Now I play this city building game called Anno Online. It's a pretty cool game no wars so less stress.

Runescape. Minecraft clasic. Moon walker.

And more.

Runescape and Moon walker sounds interesting. What type of games are those ? I mean city building or what.

As for single player games I have to mention Candy Crush. This is a seriously addictive game.

Runescape is an castle age game. You need to work for xp. So you can get better armour.

Moon walker is not that special its just an space emulator XP

The first online game that I ever played was Doom 95 back in the 56k dialup days. After that, it's mostly been Counter-Strike, Quake, Unreal Tournament, Rocket League and some random MMO games here and there. I enjoy the multiplayer experience much more than the singleplayer games simply because you meet so many different kinds of people.

I like to play online multiplayer games, mostly war games.
I like to defeat other troops.But I have not seen many active game sites.Mig33 was a favourite.

Only agar.io. Shameful huh? Besides that, maybe some lazy games on Coolmath Games or something.
But if you mean online games that connect to the Internet I've played Garry's Mod, Robocraft, and a bunch I can't remember.
