Ive played several games on prince and emperor now and have three little pet peeves that if I had the skills, I would attempt to tweak with a mod. Here they are. 1. Rivers count as a city connection. Two cities on the same river should automatically have a city connection just as if they had been connected by roads. It's thematically and historically accurate. Require Sailing if you want. 2. Early Unit Maintenance. I think this is the biggest problem with lack of early gold. By the time you build a scout and a worker with your initial warrior, you are at your limit. You can't even afford 2 archers to protect your worker/tile improvements and your first trade route. I would have it scale down rapidly after 100 turns, but a couple additional unit support early would make a big difference. 3. A carryover from G&K: freakin' mountains and observatories. Settling right next to the mountain is so often not the best tile to settle on, but if you want an obs later, you have to do it. I just never got why you couldn't put that obs on the mountain you can see from your loft in the city, still inside the 3-ring workable border. I have the G&K mod for this, but I'd like to see it become standard.
