Does this apply to dungeons and dragons as well?
In D&D I'm almost always the guy who has Savage Species cracked open, and want to play something different. I would rather play a monster. Often, I resign myself to playing a support character- as in, a secondary character to the story arc- but that's fine by me, as long as I get to try something more to my tastes.
Since I'm playing a monstrous race, I choose an earthy fighter or ranger- type most often- something more in tune with the land than a 'normal' race can initially be. Also, monsters can present challenges both to play as well as to DM. Often a monster has a wicked edge in certain situations- but severely lacks in others, way moreso than the minor imbalances in the standard playable races. Due to the imbalance, this often makes my character a secret weapon or a heavy hitter, one that strikes, then gets out of the way.
My newest character is a flamebrother(salamander) cleric, in a battle against vampires. Good support role, but can definitely shine(ahem) on his own.
