Personally, I'd much prefer not to. The decisions whether to build a Worker first, and when to build your first Settler, are two of the most important decisions in the early game. Just giving those things to everyone kind of kills a lot of the early-game strategy, and doesn't really teach you how to play a "proper" Civ4 game in multiplayer (you have to remember that a few people in this game probably have not played MP before). Not to mention, starting with a Worker majorly unbalances the game for the civs starting with Worker techs (namely Agriculture and Mining, but also The Wheel and Hunting). Civs starting with one or two of those techs are immediately at a considerable advantage. Meanwhile those who start with Fishing or Mysticism (or both) get more hard done by, since they have to research the Worker techs before their Workers can do anything.
I'd much rather play the default game as it was intended to be played, without modding the map or the starting bonuses in any way.
