To be honest, we're not sure what the standards should be. Generally, if someone made your game more enjoyable and they represent a player you would love to play with again, they are worth Honoring. We'll figure this out together with the community and adjust Honor accordingly.
I really like this idea, but one thing I fear is that people will confuse doing well in the game with being worthy of "honored." Do you think that there's going to be a strong correlation between being the victor/having a strong score than just being a fun person to play with?
