Looking for more hints? Wait a few hours if nobody guess the game I will tell the price and that kind of stuff.

Agarest: Generations of War

Thats right! your turn, sir!

its usually very cheap at the sales and I've pick my steam copy at the tier 3 of some HB two years ago, I guess..

Yeah, I don't $60 want it. :P Maybe later.

Back to the game.

Okay. next

In first place I'd like to try a very wild guess:
Virtuoso?

edit: lol... nothing to do with that game ^^

The previous clue applies for this game too...

Quake 1

Yep, Quake skybox :D

You again.

It was a hardone. I was looking for games like descent but isn't here on gog anymore. Then FPS... I know that I've seen that texture before but I never expected to find it on quake's sky

Here is the new trivia. Available on GOG.

Looks like Freedom Planet.

and, in effect, it's!
your turn!

Here's a real tough one.

It's surely Police Quest ;)

I think there were slightly less stairs on that quest...
