Something like a grand strategy game with teams maybe? Or even something like team online Risk? Seems like it could be a good time.
Something that you can get into for a couple of hours without a massive learning curve, I guess.
Do online team or co-op text based adventures exist?
Thanks everybody for the recs. Lets see how much malware is on game torrents.
Another one I will add is Mobius Front '83, which is a TBS that is challenging without being as heavy as my other suggestions. I haven't played it on multiplayer yet, but I think I'm gonna gift it to a friend of mine and give it a go soon cause I've been enjoying the campaign.
