Hi Ozzy4242. Welcome to civfanatics.com.
Yeah, it’s a quick start. The mod is mostly a way of easing you into a modern start (mainly for the benefit of the AI).The ‘Developing Nation’ age is just to weed-out unlucky AI players. When you enter the ‘Competitive’ stage the pace will be noticeably slower. About the map, it’s a post-apocalyptic world so people will still have a world map.
For a good start immediately change government type, spend a good chunk of your cash buying tech from the AI and rush production on town halls. Things will stabilise pretty quickly. I hope you’ve not got it on Chieftain.
Good luck and have fun, Oni Ryuu.
P.S. If you want long-term games Civinator has the CCM and RARR mods and I’m due to release my TLC masterpiece (ego intended) shortly.
