*sighs* It is a SINGLEPLAYER GAME! Duh!
As long as steam is in offline mode you can.
@Darth many singleplayer games now require an internet connection to play, you didn't need to be so hostile.
The time of release of the game, as well as the lack of any drm other than steam on it should have answered the question, I just get sick of questions like this that could be answered with a google search or basic logic
Do take note, however, that if you play offline, you may encounter problems with achievements (e.g. You not getting it even if you defeated a boss) so it's still best to play it online if you want your Steam achievments to reflect (almost) in real time :) Good luck!
What has the world come to when a person has to, and is right to, legitimately ask this question before making a purchase of a single player computer game -_-
Well since EA F***ed up the new sims i've become highly sceptical to ALL singleplayer games. Even if they don't usse origin.
be locally save since you will be offline. If you ever remove the game and reinstall windows you have to atleast sync the game once by running it during online to syc files to steam cloud so that you don't loose you progress.
