I just finished playing an Ice Age game with wide continents. While I enjoy the barbarians in the early game, it can get so incredibly frustrating and time consuming to deal with them in the modern era. I had a huge tech lead, but as soon as I got the technology for destroyers and infantry, the barbarians started spawning those units like mad. The rest of the world was using musketmen and caravels (At this point I had conquered most of them and crippled the rest). On certain map types (especially ones with many islands or uninhabitable areas) the barbarians never start spawning because some parts of the world will always remain uncivilized. It just seems like an unnecessarily time consuming annoyance to have destroyers randomly blockade your cities in the late stages of the game, and not get any experience for fighting them. I'm looking for suggestions on good ways to deal with them without disabling barbarians, as some civilizations and policies depend on them, and it wouldn't be fair.
