Gaming Online games to play with friends?

[Hells Malice]

Have they stopped developing the game?

THat's a shame. It had a really nice art style and showed a lot of promise.

Nothing official, but the dev went silent since...july? I believe it was, and the last real update was early july as well as I recall.
The dev recently made a tweet or reddit post or whatever the fuck social media bullshit he uses to say the game isn't dead, but I honestly think its just an attempt to lower the heat a bit while he continues to run off with the money. /shrugs

Here are a few that my friends and I have enjoyed playing:

Borderlands 1/2 - others have mentioned these
Halo Custom Edition - crazy mods and maps (Zelda, Mario, Sonic, etc )
Age of Empires 2 - old one is still great, but HD one on Steam is modern computer friendly
Guild Wars 2 - action and team oriented mmorpg (buy once, no subscription fees)
Modded Modern Warfare 2 - lots of fun possibilities
Chivalry - medieval combat, ctf, objectives, etc
Monaco - top down stealth coop game
Castle Crashers - multiplayer beat em up like classic TMNT
League of Legends - online battle arena
Minecraft - before all our favorite mods were discontinued...but still fun if you haven't played it yet

Hm... Halo... He used to play semi-professionally! Does it have viruses if I download it???

It all depends on where you get it from...I don't think you can buy it digitally - you have to get a physical copy to get it legitimately.

Killing Floor is pretty fun, tons of gore and such but in a goofy way (by goofy I mean morbid and horrifying.)

Gmod is awesome, you and your friends can do whatever the fuck you feel like on that.

Pretty much all I can think of that hasn't been suggested, i'll edit if I can think of more.
