I lumped these together because they work together, but also because I only have a few thoughts.

Specifically that bringing up an unplayable card (taking some equipment that is currently trash would be the CF equivalent) doesn't actually constitute power creep (at least according to the video). Making a weapon or piece of gear that would otherwise never be used and making it good enough to be used in play (by vets, because a newb may not know any better) doesn't actually break anything. No matter how many avg. 15 weapons are available at level 15, you're still going to upgrade to avg. 20 weapons... so why have anything be below avg. 15?

There is also some very interesting things about un-comparables... Things that aren't directly comparable because they're different enough they don't fall into the same niche.

CF also has the advantage of going back and rewriting the past. There is no published decks like in a card game, so you can adjust gear dynamically. Defiance is now avg. 25 for example is a straightforward thing to do in CF, but not a CCG. On the other hand, edges weren't dialed back in the same way, because current characters didn't lose edges... Which was a weird situation that I assume we're out of now.
