A game session is a party.
You don't judge a party on what things you brought to it (how clever or sophisticated they were), you judge the party afterward based on how it went . Did people you like have fun? More fun or a kind of fun you wouldn't have had without the party?
Things you might sell or trade or pick-up to use at a party are only as good as how much they improve the party . If the people had fun every time, and those are people you value, then whatever they were doing was correct .
+Zach Marx Weber brought lasers to a party once--it was a good party, at the party below, there were no lasers, and the band that was supposed to play didn't show up. It was a very good party anyway. Somehow. We had a Red & Pleasant Land cake, but I don't think that novelty was the deciding factor that made it click.
If it works: you can't smack it.
A clever, innovative party ceases to be clever or innovative if it leads to a bad party.
The play's the thing.
