Hi All. I am new to ESO. I joined to play with some friends who also play. I have a quick question. Does anyone know if we all need to be on the same expansion to play together? Right now we all have Morowind. I am considering getting Summerset (because it is on sale until Dec 11) but my buddies don't want to. If I get Summerset and they do not will we still be able to game together? Thanks in advance for your response.
