Dark templar? No.

Another image (same game):

Added color to the images. Should be easier now.
And made a new image (number 3).

Starcraft or something like that?

Yes!

Thanks, I wasn't sure after the first two pics (1st one looks like some protoss thing and the 2nd one is pretty zerglike), but the 3rd one with the terran medic made it a lot easier to guess.

Will post a new riddle in a bit, off to the drawing board!

next riddle ready mateys

hint: it's not Ultima Underworld

Port Royale

And is that rat giving me the finger!? Those little assholes think they can do anything just because they're cute and fuzzy.

It's not Port Royale but you have cunningly devised that it has something do to with ships, this will make the guessing easier!

(and yes, this is a rat with sub par upbringing)

For the sake of keeping the game alive... The Ship? :P Seriously, I have NO idea.

A little help: Since it's a ship game where you pay in dollars and not in gold, all the pirate themed games can be excluded. The game may play during modern times, the game itself however is quite old as can be seen from the old school interface.

I only know about 2 or 3 games where you manage modern ships, it's not that hard :) It's not an obscure game at all, just a bit old.

That's the game, yes! Not surprised to get the answer from a German, the game was quite popular here in the German speaking lands (Germany, Austria & Switzerland).

Ports of Call isn't all too exciting as a single player game but with 2-3 people on one computer (hotseat multiplayer) it is surprisingly engaging, even if you're not into managerial stiuff / number crunching.

I do not know what to draw so someone can take my turn.

Fairly obscure game that one of my buddies in college owned.
