Most games released by EA that have now returned to Steam require Origin to play apart from a select few from a certain year and before so any game from I believe 2013 maybe earlier you still need Origin to run to make it work if you buy it through Steam, thought some latest games dont it's a bit mix and match with EA for example Star Wars Squadrons does not need EA running to play it on Steam.
Dont ask me why some games do some dont but for me personally if I am going to buy a game I'll find it cheap as a legit site not that g 2 a con site and just use it's launcher i'd rather have it on steam yes but i'm not having 2 launchers running for a game when 1 is enough. Personally if you bought it legit through Steam that running should be more than enough
