UT CTF - Large 8-16 players. Doctor Suess dust-speck city! May 2003.
"Whoville Wars" was a Large CTF map designed for the Unreal Playground Doctor Suess Theme Mapping contest held during May 2003. This was to be a the Whoville city on a dust-speck (sort of a mini mini me map) from the Suess story "Horton Hears a Who".
Turned out to be far too much map to pull off for a one month mapping contest, so I never finished it, nor wanted to afterwards :P
I do recommend some of the other Suess maps that were completed. I don't think there was ever a map-pack made for this contest, however, all Suess contest maps were identified as "CTF-DRS-name", so should be pretty easy to find among the thousands of UT maps available for download in the current UT archives on the web.
