Discussions on Starting Location Characteristics and City Booster Spells, ie. Making the Start Less Rigid. =)
Since the first city is so important, and often you have to restart many times to get a really good starting position, why not either start the game off with all players having a high resource city and the Sov on top of it, or make the city the Sov creates always a choice of 4/4 or 5/3 city if there are no better tiles around, and all cities afterwards created by Pioneers rely on the underlying terrain.
Also, while we're at it, since it is generally required for any decent game to cast Inspiration and (if you have it) Enchanted Hammers on your starting city, why not boost the starting city (capital) for each faction so that it creates more research and production? Only the biggest city for each faction would get the bonus (subsequent cities wouldn't) and if another side captures it it loses its Capital City Bonus (and then gets it back if the Sov captures it back).
