So yeah, Steam users can't buy the physical version which is already total bullcrap, good job Square and Valve on screwing over your costumers, really.

Now a friend told me that Steam users are also not allowed to buy a standalone version (I.E. from Square) and play on it because of account restrictions??

Is this true? Can someone explain this please? I don't want to be chained to Steam until death do us part, if something changes and I don't like it, I wanna gtfo.
