Y is for Yes

   As in say yes to your players wild schemes. Put a cost on it but let the players do it. A player can come up with the most outragous of ideas from time to time but properly done these can be the highlights of you game. So what if they want to swing from a chandelier, jump off it, then land in a roll coming up behind the enemy and doing a surprise attack. Its fun and exciting and if they fail and fall on their face it can get a good laugh. Most of all though is that being able to do these kind of things is something tabletop roleplaying games have over computer games. You don't have to make it easy but at least you can let them try.
