How to buy an old game?

Hello dear experts.

I am writing to you from the capital city of Kuiva to ask the following question:
I recently downloaded the fun of a wonderful torrent, which is called “Dark Reign: The Future of War”.
And I started thinking to think, am I breaking any rights?
In stores / markets can not see it. In Aktivizna and its pages left.
I did not become like a creeping reptile. And if so where should I carry my pennies in order to wash off this evil spirits.

Well, actually what in similar cases can say our law? Those. when the game is no longer supported by the publisher, and is it not possible to sell it to download it without fear of consequences, is there any time limit after which the software becomes free of copyright?

PS: Karma drove below the baseboard, thank you all, for now, I won’t get out of it for it’s a long time, but I’m afraid there’s no sense, I’ll remain who I was before and everything will happen again (fixed, thanks to those who understood)
