Hi there,
A World League...hmmm...I knew I wasn't the only one who'd come up with such a great concept
!
A correction if I may, the right word in Spanish is Habaneros, with "n", not "ñ". And, to be perfectly honest, that nickname wouldn't sell very well in México. So, I'd suggest another nickname, perhaps...
Great ideas for your logos though! I've a few pics of international stadiums fit for OOTP X (Foro Sol in México City, Hiram Bithorn Stadium in Puerto Rico, Tokyo Dome, Jamsil Stadium in Seoul, etc.) and I'd be glad to share them. Just let me know if you're interested and I'll be more than happy to send them to you.
