No Welsh. Britons or something, maybe, to reflect the culture of the British Isles as a whole. You could have King Arthur as a leader. But no Welsh. This is a game about civilizations, not every tiny little country in the world. If you're going to include the Welsh then you're going to have to break up all the other civs into their constituents and represent groups that are currently only represented by a notable nation, eg the Iroqouios will have to be replaced by about a dozen different native nations and so on. If you want Wales, mod it in. That's what the editor is there for. If you want a culture to represent pre-Roman British Isles, I'm all for it, but I'd pick the Irish before I picked the Welsh as a representative, and I'd rather call them a more encompassing name like the "Britons" to represent them all. I have nothing against Wales - last name Griffiths in fact - but it's absurd to include all the small nations in the world in a game called "civilization". There's no such thing as "Welsh civilization". There is Welsh culture, a Welsh nation and so on, but its part of a larger civilization (Gaelic or Celtic Britain), and if we do that every civ in the game is going to have to be broken down and a bunch of others included. The Iroquois will become the Iroquois, the Cree, the Blackfoot, the Huron, the Algonquin, the Apache, the Cherokee, the Haida, the Navajo, and about a dozen more. The Greek will become the Athenians, the Spartans, the Macedonians, the Myceneans, the Minoans, the Trojans, the Medeans, the Lydians, and so on. By the time they include everything that everybody would want, make up animations and UUs for them all, and do all the research to make everyone happy, the game will cost you $500. That's why people do mods, so the more specific things they want can be in the game.
