One important thing to do BEFORE you game with anyone is to discuss these things. Make it a habit. Does your opponent want a historical game or do they want a fantasy football type of game where everything is good to go if you have the points for it?
There are different rules at CM specialty websites that have things like rarity rules and "Fionn Kelly armor rules". Take a look at all of the links here:

Personally, I like the more historical games, but do delve once and a while in the other type.
So, remember to talk about these things with your opponent before you play. Whether it is over the phone or by email, you will be happier if you get things all laid out -beforehand. In terms of email, go ahead and make a generic email and save it where you list all of the things that you want. That way you can cut and paste it each time you play and work out an agreement -beforehand. Your opponent may end up being impressed and grateful. The onus is on each player in my opinion to set things up for their greatest enjoyment.
As to what you wrote, I personally don't think it is gamey because it wasn't discussed beforehand. What do your opponents think you are? A mind reader?
