Quoted from TKDalumni:GOT and SW for sure. The rule sets are amazing and the Pro's play faaaaaast. Honorable mention to DP and JP, but the premium features are much better.
SW and GoT - yes! Those are my two pros! I simply do not get sick of them.
I would prefer the premium of each, but like the fact that I won't lose money on either if I ever have to sell them.
