Inspiration
I love this rule. As GM, keep a few tokens of some kind with you every session, at least one for every player. Whenever a player does an excellent job roleplaying, performs a heroic action, or really anything that gets the table going, give them an "Inspiration" token as a reward. Each player can only have one token at a time and it can be turned in before any d20 roll to give them ADV on that roll. This is a wonderful way to reward engagement that publicly recognizes a player's contribution to the group and gives a small, but potentially dramatic in-game effect.
GM Note: Give these out freely! Try also to reward different types of engagement from players. Not everyone is comfortable with accents and grand speeches (guilty- I am hopeless at voices), so pay attention to your players. Noticing and rewarding when they step outside their comfort zones can go a long way towards building comaraderie and trust within the group.
