Re: BFII on Origin after you buy/add another edition from a different launcher
To give a definitive answer to this thread:
1- By adding BFII celebration edition from EGS you keep all achievements, hours played, milestones, and all previous progress you had in-game
2-You get to keep your origin BFII Deluxe/standard edition, and the preorder skins that come with it
3-There will be 2 BFII titles in your game library, one with an EGS label (needs both origin/EGS login to launch), and the other you had prior (requires only origin login)
4-EGS will both be its own title and merge with whatever origin edition you had, celebration will act as an add-on if you had the standard or deluxe edition
5-You can invite friends from origin despite owning it on EGS, as they both need Origin to launch
