No, this is not Hearthstone.

Yu-Gi-Oh! Legacy of the Duelist?

Yes that the right one.

I like that game. Unfortunatly this game gets no updates or newer cards anymore.

I recognized Yu-Gi-Oh right away, but needed to do some google imaging to find one with a similar interface.

Anyway, next one:

Wild guess, but it's the first thing that comes to mind : I have no mouth and I must scream?

The first thing that came to your mind is correct! Your turn!

Wow ok, that was a verry lucky guess - I really should make time for that game one of these days.

Here's the next one:

It's from the very first image you see on starting the game (after the usual publisher logos/etc), so you may have seen it in screenshots.

Ah right I see, that might be it then.

As for the clue, I'll post another one a bit later today when I have a chance to take another screenshot. I will say that it's from the final video clip of the game in question.

Not necessary to post another pic. It's ANNO 1503, also know as 1503 A.D.

Which is btw the second time Matewis posted the game recently (last time was the end of April as far as I remember)

Aw I was hoping this would be tough one. Figured few people would recognize the victory cinematic of 1503.

Your turn :)

Ok, where do you have such a nice prospect?

Look at this shadow.
