Re: VnV GM Tips and Advice
I keep a notebook with stats on all of the baddies and pretty detailed notes on how characters are handling challenges. I find it helps, especially if there is a RL hiccup or pause in play.
I also try to take notes of what is more powerful & less powerful than I thought it would be in-game. I find it's easy to over or underestimate a characters (especially a Villain's) effectiveness in V&V. When 1 guy is taking on a team of 5, something that seemed like a "level the playing field" power can actually be a game breaker (otherwise known as a good-guy killer- which I DON'T like in a game- as a player or a GM) OR a pillow-fight power, not actually doing any damage.
Keep in mind, that my style of game is to make players sweat, but not actually die, and think to avoid further complicating situations, as well as consider matters of "Super Power Ethics."
Your style of game may be different :)
