Take this for what you will. For me, its more a group ettiquite and respect thing more than anything else.
Of course, not everyone in the same group is going to be as enthusiastic about a particular game. Unfortunately, this is the situation with my group and Shadowrun. But, if I am willing to put forth as much effort, work, and respect (on all levels) for soneone else's game that I may not be as enthusiastic about...can I get a little when it is MY turn?
It reeeeeealy irks me when people just give up, barely try, and just go through the motions after I'm put in the situation of doing all the work the game requires just to turn around an phone it in later or worse, try and speed things up to "get it over with" (usually to go back to the game THEY want to play). Hey, I understand that not everyone likes the same things, but if the group (emphass GROUP as we do a majority vote) gives me the green light to go ahead with a game, let me have my chance as I have given you yours. And if as a group especially, you honestly don't want to play my game, hey just be honest with me BEFORE I write up a story, create NPCs/opposition, Maps, get out and organize my books, and spend money getting the character sheets (etc) that the PCs will need.
