Ah, yes. The old "I'm getting so sick of these threads that I don't like and are clogging up this forum so I'm going to make a thread to further clog the forum up" post.
I never understand people who take issue with how other people play a game. Its not like any one here is forcing any one else to use any variant posted. If you don't want to, don't. I'm pretty sure everyone who has ever posted and/or used a custom race has probably played the vanilla game several times already. But oh no if some one isn't playing exactly like you are, they must be doing something wrong and trying to "improve" something that is already perfect.
What makes this particular type of ignorant arrogance even easier to dismiss re: Small World is that the base game comes with blank banners and encouragement in the rules to create your own variants. so custom races is in fact part of the base game!
