Same, I just can’t place it.

For some reason I’m thinking TD game with a discrete mission structure.

Maybe something like Defense Grid?

Nope, 'fraid not, but I like the reasoning quite a lot. Run with that again next screenshot update, perhaps.

Aaaaaaah, it’s Infested Planet?

Nope!

I’ll say Unstoppable Gorg but it should have concentric circles so I’m pretty sure that’s not right.

Okay, here is where I think it gets a touch easier. Good luck!

AI War? I think the text might be in the wrong part of the screen though

X3: Terran Conflict?

Dawn of War II: Retribution

Great guess.

The text is the giveaway, and I was just playing the base game so it’s either Chaos Rising or Retribution.

It looks fairly new, but I can’t place it.

StarDrive 2?

Ding Ding Ding! Well, I honestly don’t remember which expansion this screenshot is from, I think it actually might be the base game? Not sure. It’s been so long, I just dug it out of an e-mail I sent to my cousin years back, and thought it might trip up a few folks more than a regular gameplay screen might. :)

You are up, Otagan!

Oh, huh. Maybe it is from the base game. That’s what I get for not hosting the co-op game.

Well, here goes.

This is almost certainly something I’ve played. Aargh, show me more coastline!

Renowned Explorers?

Nope.

There’s plenty more coastline in your future if nobody gets it.

EU3.

80 Days?

Nope. I didn’t honestly expect anyone to get it from that one but wanted to see if it would happen. Now I’ll give something reasonable.
