Conditions

Has achievement
Checks if a player owns one of this game's Steam achievement.

Player bought the game
Checks if the current user actually bought & owns the game. If the "Require Steam" checkbox has been checked in the game properties, this will always be true as Steam will not allow to launch the game if it is not owned. Can be used to display an anti-piracy message instead of straight up blocking the launch of the game.
