It is also one of the easiest Free League games to get new players into, as you don't need 2 to 3 different distinct sets of D6 dice, but is more complex than TftL for those that like to have character options. I also love Mutant Year Zero and Forbidden Lands (also their original IP) but needing to keep track of which dice came from attributes and which from gear when pushing is somewhat a pain.
This is certainly true about Coriolis, and to be honest, one of the reasons I haven't run a lot of the Free League stuff that requires "interpretive dice". You can buy sets of dice for Coriolis and Vaesen,for example, but they're not dice with funny symbols or distinct in other ways.
Good tip, and good idea. I'll bear this in mind if I ever decide to run those games.(Tip: When players don't have enough different colored dice for this, I make a 'play mat' for them with a sheet of paper. Draw some labeled boxes on the paper, and they roll each set (Attribute, Skill, Gear or whatever per the game) separate, and put the results in the box. Then if they decide to push, they roll and return each set separate to the box, then count results. Takes a bit longer, but keeps out confusion as to which dice where from what part for effects.)
