Since my first round of additions (the new tech tree and the associated content for the new techs) are up on the SVN, I'd like to create a few threads for more proposals, but segment them off into subtypes. This is the first thread, for new buildings. I'm not a big fan of having every possible building that people have ever built be in the game; that way lies a lot of clutter. There are two conditions that I'd like any new building to fill at least one of, and preferably both, before addition. These conditions are: The building enhances a technology that currently doesn't have enough content. I would prefer not only having techs with no content at all, but also not to have techs that are only "one-trick-pony" techs. We currently have 4 techs with no content (Telegraph, Microprocessor, Hydroponics, and Neural Networks) and another 45 techs that have only one immediate bonus or a handful of small bonuses to existing items. The building forms a line with existing buildings, such as the Palisade - Walls - High Walls line. This reduces the overall complexity of the addition when playing with the Hide Replaced Buildings option. Either the new building will be replaced by the old, so that once you reach the old building the new is no longer an option, or the old building is replaced by the new, and the same applies. For example, once you have Masonry, you shouldn't be able to build Palisades as Walls are more effective. This makes more sense to me than (most) buildings going obsolete; you don't usually lose a building from technology, but the building gets abandoned once something better gets built. I'm also willing to take requests, but keep in mind those two conditions. Buildings aren't that hard to add once you have an idea, because you can get by with just text and a button. You don't have to have building art, especially if it won't be seen in-game.
