There are people who a fans of star wars upto the original three movies and thats it and there are fans who like the OT AND some of the MANY aspects of the franchise.
I would take Malak over Tarkin in a second, i mean tarkin is an old bloke in a suit that didn't do ____, that'll cost $100-$120 and Malak is a Sith Lord in a unique costume with detailed jaw and lighstaber and would run for the same Price
Wanting the OT figures is great, but there are better characters out there too who have fans too, and OT snobs just don't count them as fans because they like something in addition to or other than the original trilogy.
Original Trilogy snobs are fans of Star Wars upto the 1980's, where as real fans continue to follow the franchise into other mediums like comics and game.
