Naw, its a great reason. Whenever someone starts babbling about it being unrealistic that an elf can shoot arrows out of the air, i always get a huge laugh. Its an ELF!! Of course its unrealistic. Its a fantasy game, set it up however you want, change any rule you want, throw logic and sense out the window. As long as its fun, its all good. But i really do get your point though. The game should at least be internally consistent.
When you direct a group of player during enough time in roleplaying games (just to mention one of the possible activities), you learn that even the most (apparently) unimportant things must be consistent. There must be a reason for them and, if conditions are the same, they should be repeatable. Games should be fun? Yeah, that's why we play. Unrealistic = Non consistent? No way that can be fun. Unrealistic = new set of rules? That's good.
So it's not a matter of:
- A: "Hey, this is cool!"
- B: "Well, two things: a) I don't envision it as you do; I don't see it as it doesn't make sense per se and you give no explanation."
- A: "It's cool. It's magic. You shut up, you are arguing. Devs will make it fit."
But of "Does it make sense?". It you cannot thing of a way for it to make sense, it doesn't work no matter how "cool" it is. And "It's magic" is the same as "Because God says so". Or "The Devs will do the work" doesn't cut it for me.
If I want to have female population to have an impact in population grow, I don't just say it and let the Devs do the work. I actually create a thread about it and try to touch some view points about how it could work (or not work). That allows me to develop the idea, make it grow, see if it can make sense, look for limits... That's my way and if someone doesn't like it, life is unfair, sue me for it. But I think that in general my posts all follow the same pattern (of sillyness but that's because I'm silly).
Anyway, /thread for me before someone gets (more) offended or something.
