Whenever I'm running or playing a game, I consistently run into an issue of setting atmosphere. I've realized the best way to do this is through more effective, engaging descriptions of settings, actions, and objects that the characters see and feel.
As a player, I feel that my actions are generally "I attack the goblin," or some variation thereof, but I'm afraid that I'll stumble over my words and further confuse the other players and I'll resort to "I attack the goblin" as to not drag the game out longer.
As a DM, my issue tends to be more with setting atmosphere with settings, locations, and objects. Effectively, the flavor texts that comes with walking into some amazing location that the characters (not necessarily the players) should be suitably impressed by. My goal here is to engage the players with some degree of spectacle, and be more inquisitive in their environment and whatever lies within it.
How can I create more descriptive, concise flavor text for the games I play in?
