I'd rather try and find more city-names!

I don't think avoiding "New Tikal" is a good reason to change gameplay.
Hey TLC,
Have you thought about making 2 other non-playable civs (Highland Maya and Puuk Maya for south and north, respectively) to cover the uninhabited areas? They could be much like Mexico and only partially habitable by players, but occupied with a few key cities in control of strategic resources like salt, black obsidian, and the like. Anyway, just a thought.
By the way, I've come up with some names for people who want more city names for each of the civs in this scenario.
Tikal: Laguna Perdida, Itzimte, Topoxte, Tayasal (Polol should switch from Calakmul, though who knows what its status was). For early sites in the build order you might put El Mirador, Nakbe and San Bartolo--or mix these three in with Calakmul, as they're all northern Peten.
Calakmul: La Corona, Punta de Chimino, Los Beremos, El Achiotal, Paso Caballos, Yala (also, El Peru should
definitely go with Calakmul, not Tikal as they were major supporters of Calakmul during the Classic)
Palenque: Morales, Jonuta, Pipha', Panhale, Santa Elena, Poblicuo
Piedras Negras: La Joyanca, El Pajaral, Mactun, San Diego, Tamaris, Pie de Gallo
Tonina: Sak Ts'i', Plan de Ayutla, Agua Escondida, Chiapa de Corzo, Tonala, San Miguel, Bellote
Caracol: Cerros, Lamanai, San Jose, Barton Ramie, Naj Tunich, Tzimin Kax
Copan: Los Zapos, Los Higos, Acasaguastlan, Yarumela, Quelepa, Usulutan, Naco
Anyway, hope this helps you out.
Cheers,
Balam
