I bought a game on steam and it gave me 2 gifts of that game with it free!! Is it normal?

what game was it?

some games give copies of it to give away to a friend, that copy you give to a friend turns in to two copies and so on.

The ship always does because it's a game best played with friends, and it is actually a ton of fun. The people you give those copies to will also get one extra copy to share, totalling five copies of the game/
