Steam versions use Steam DRM, no other DRM is added.
Non-Steam versions (digital or retail disc) are as follows:
- No disc check, you do not need the disc in drive to play.
- No limit on the total number of PCs you can install and play the game on.
- There is a limit to the number of unique/different PCs that can start/play the game within a time window [5 PCs in 24hrs].
- Each install requires logging in to your EA account to verify game ownership and if you are a member of these forums, you have an EA account.
- You can play offline but the game will require a login check after a select period of days.
Release Control (does not use securom)
. It does not install anything to the PC.
. Sole purpose is to check with a server to validate whether the game release date has passed or not.
. It completely removes itself after the game release date has passed.
. You will not be able to play until that date has passed.
. Dates & times are set to the retail street date per country.
Hopefully this explains the DRM included in Dragon Age 2.
