Dragon Age: Origins you should be safe, last time i checked it had no severe DRM and it came out long enough before Origin for EA to stop giving a shit about it.
DA:O had other issues, in that it tries to authenticates your DLC
every time you start it up - and if it couldn't find the authentication server for any reason, then all the DLC content was stripped from the game. I messed up my first playthrough as a result of that, because even when it did manage to reconnect to the server it didn't restore everything properly (my Blood Dragon armour and other DLC-related items went missing from my inventory, for example).
There's an option somewhere to make it only check the once, but for a lot of people it was too late by the time they found it. OP, if you do get the game, definitely uncheck this option after first authentication!
