Yes, they should be, but there is problem with M:TW Gold that gives compatibility issues in MP: basically the game says it is M:TW 2.0 (M:TW + VI unpatched) while it should be (and appears to be) M:TW 2.01.

Also, what the difference is between having a Gold edition of MTW/RTW and having the 2 games and their addons as separate items?
None whatsoever, except for above caveat.
