Who ever you play MP with with need the same mods, or no mods enabled in order to play together...without CTD as BBW said
I although have found in MP that I can add in as a mod using JSGME, my sub ( and the others sub if you wish to see something other than stock, or what they are piloting), OLC's GUI, and also GWX Cpt americas Icons...and I will still be able to play or host even though the other player doesn't have those mods
