Back in my teens, we had several LAN parties with Duke 3D / Quake 1-2-3 / Counter Strike matches overnight. I even remember a couple of instances where all of us were playing single player Diablo 2 and even The Sims "together".

Now over 35 with a family, working overnight on projects with a deadline is a more regular occurrence. Firewatch came close one time. Oh and when my wife and daughter went away on holiday last year for a week, I had a few nights playing GTA V all the way through. Alas, they came back. :)

Hm, thought multiplayer was a default feature on the main screen. I installed the gog version on my laptop and never saw any difference, I'm sure there were times I went into multiplayer just to spectate on my gog version. I really don't think there is any difference except that gog allows you to install whilst offline. Really should not be any issue.

OK! Then I will get the GOG version first with the expectation that everything should work. Then, if it doesn't I can try the Steam version last, but hopefully that won't be necessary, and I will only need my pure and holy GOG DRM-free copy :)

I think I recall now, when I wanted to get into multiplayer I had to retrieve a serial key. Not an issue, I just keep some basic note file with my gog game in case I want to log in and do multiplayer. Just another step which you don't need to deal with on steam. I think it asks you for your serial key when you say you want to engage multiplayer.

Oh, I did that many times.
It's quite bad for your productivity and health in the long run, if you exaggerate..

Not all night since an AD&D session at a con 20+ years ago. Not past 2 am for a few years iirc, and past midnight has gotten pretty rare. I'm more often up early playing on the weekend, because I get up to walk the dog while everyone else sleeps in (and I'm more of a morning person anyway).

Early morning gaming with that first cup of coffee is pretty glorious though :)
That is, provided you got a good night's sleep...

With the old Civ... The sentence "One more turn and I go to bed" has caused an insane amount of sleep deprivation.

Exactly! If I slept properly, I'm actually better at platformers/twitchy games early in the morning.

Into next morning? Try over a whole weekend... but it helps to play fast-paced fps tournaments and alot of cola...

When I was younger that is :-P

Wait. It's morning? :)

I don;t recall any overnight but I recall a few until 2am or so.....

Now you know how people in Alaska feel.

Ah I'm suddenly reminded of that old video of the Halo 2 player falling asleep and snoring through his mic at 7 in the morning XD

Yes, Yes I have. Many times.
