I happened to stumble upon this site when looking for new background musics for my rpg sessions; it's really worth checking! I am now categorizing them where they fit best (scifi/space, fantasy or both (or something else)). For my purposes, it was searching music with 'epic' feel that gave me what I wanted.
When designing or running an adventure, you need to be careful about how you use details. While details can make a story alive, they can also make your players fall asleep.
A little but invaluable tool I've used in my 4E games. I mark up player characters' passive perceptions and insights, plus any other important notes (that don't need to be secret) on this sheet, and when it's time to fight, initiatives are easy to mark on the left side of the sheet.
Below the tables there's a large empty space; you'll find use for it when you start calculating hp's of the enemies!
You've most likely seen the prequel movies, perhaps also watched the Clone Wars series. While everyone doesn't like them, or even hate them, one thing can be said for sure - a character concept that is perfect for roleplaying games exists in them - Jedi. The jedi lead, fly, negotiate, investigate, fight with blazing swords defeating loads of opponents - they are HEROES. And perhaps you've already noticed that some stupid movies would work extremely well if they were roleplaying games, as players love to do stupid things even if they don't like watch someone else doing such!
Every GM has her own tools of the trade, little tricks she uses in his games. Sometimes you can just shake things out of your sleeve, but sometimes it's good to have some kind of tool you can use when in doubt. A tool I've used for years is a Luck roll, a simple d6 you roll for the character or group doing something.
In a recent discussion about roleplaying mechanics I heard an opinion mentioning that character flaws should be a disadvantage and therefore rewarding well for playing them isn't something that should be done. My way of looking at flaws is completely opposite. While flaws are in general supposed to be a tool of balancing (or in practice min-maxing) characters, they work best as a tool to bring atmosphere, good story and drama to a game. And for this purpose, they work best if players want their flaws to cause them problems.
Traditionally, most fantasy miniatures represent warriors, wizards and other combatant or adventurous types, and even then only people. This leaves many of us gamemasters want more miniatures, both for scenes taking place in the middle of crowds or where larger, more exotic weapons are used in combat. There are some such items various manufacturers are producing, but mostly they are metal miniatures, and many prepainted miniature collectors want to stay away from those metal ones.
