Here's the problem I tend to have. I'll come up with a cool idea for a character or a campaign and will get excited about playing them. However, what will happen is after a month or two of that campaign I'll realize that there's this other cool concept or idea. And its not just me either. My group has too many good ideas and there's no way to play them all.
So does anyone else have this problem ever? If so what do you do about it?
