Hmm...I've played KZ since it came out, and have been in some #1 clans (ROF, Hc, etc.), and I've never heard of CRU (but I have'nt been on regularly for the last 6 months or so).
GODS had a 64 game winning streak and held #1 position on gamebattles for the first 8-12 months...with no other clans coming close to breaking that record (yet).
My tag is PowerPaul...but I only play here and there nowadays.
