This page so needs more information on it.
Anyways, seeing as this wikia is relatively active, I'm going to put here that in Advance Wars DS, the maximum rank achievable is 100. After moving from rank 99 to 100, the rank number turns into a gold crown. Rachel then pops up and basically congratulates the player on reaching rank 100, thanks them for playing, and tells them that the original Famicom Wars was released in 1988 and it was called Famicom Wars because Famicom was the name of the NES in Japan. I think she also mentioned that NA got the Advance Wars series in 2001.
Don't have an exact quote, sorry. Saved without thinking, and not sure if I can get the dialogue again. -Akira 03:15, April 10, 2012 (UTC)
