online co-operative games, engagement, and Resistance 2018

I'm a big fan of online games, and there are loads of creative ones out there. But I've been thinking on it for some time now,  and I haven't quite yet run into what I'm picturing in my head as an engaging, multiplayer co-operative online game. Two players, I'm imagining, working together at some goal, each using resources the other lacks access to. Not sure what that would look like just yet, but it's floating around in my mind.

One path I started thinking down at one point is what that would look like on Twitter. The relevant question is: "how could two people interact to reach some shared goal, via Twitter?"

I don't have an answer for that yet, but evidently I'm not the only one thinking on it.

 

One thing that caught my interest is the Resistance 2018 project, engaging fans of the upcoming Terminator movie. By following @Resistance2018 you'll get connected to Terminator backstory tweets and engaged in extra plot, as well instructions on how to participate in the twitter-based game.

The setup is simple, but shows some promise as a foundation for future projects to build off of. Essentially the way it works is this:

@Resistance2018 tweets one of various types of prompt to all of it's followers, coded with acronyms like RA:PT, SW, TSU, etc.

Depending on the type of prompt, followers either complete a fill in the blank, word scramble, answer a trivia question, or they are updated on part of the Terminator backstory. Properly coded responses (using the correct hashtags) are submitted via @ reply, and added to a profile scoreboard if correct. Leaderboards are of course involved as well.

Full instructions here. As I see it this is a basic but stellar start - great setup, would love to see something more inventive than word scrambles. Looking forward to seeing more great ideas to follow.

Have you guys run into any other engaging Twitter-based games?
