Prosperity

You're the leader of a great nation which is currently expanding. Over the course of the seven decades covered by the game, you will have to invest in infrastructures and industries, provide your country with energy and invest in advanced research in order to remain competitive.

But prosperity has a price. You owe it to future generations to leave them a healthy world. Pollution lurks, but will you be able to limit it?

Prosperity has players building up their countries on a grand but abstract scale, with them needing to balance concerns over energy and ecology with the constant need for capital and the long-term goal of prosperity points.

The game starts with 24 tiles available, half on the energy side of the shared game board and half on the ecology side. Two tiles on each side are placed on levels 1-6, with the players each having two research markers energy and ecology that start at level 1. Each player has an individual game board with color-coded spaces for tiles, a pollution track, and tracks for energy and ecology. A stack of 36 tiles with tiles arranged by decades: the six from 2030 on the bottom, then the five from 2020, and so on to the five from 1970 is set up during the playing area.

On a turn, a player draws the top tile from the stack, then everyone resolves the symbol highlighted on the tile:

Energy for a positive value, earn money; for a negative value, lose money or increase your pollution
Ecology remove or add discs to your pollution track
Capital earn money for each capital symbol on the tiles you own
Research advance one research marker one space for each research symbol on tiles you own
Prosperity score points for each prosperity symbol on tiles you own, but only if your pollution isn't maxed out
Once everyone has done this, the active player takes two actions, repeating an action if desired. The possible actions are:

Take money.
Remove one pollution marker.
Move forward one space on one research track.
Buy a tile, with the amount owed being based on whether the tile is energy or ecology and the level of your corresponding research marker. If you buy a tile of the same level, the cost is 100; if the tile is of a higher level, you pay 100, plus 100 for each level; and if the tile is lower, you pay a flat 50.
Players have limited space for tiles on their individual boards, especially since the tiles and spaces are color-coded, but players can cover existing tiles, if desired, losing any benefits (or penalties) in the process. Some parts of the individual board are off-limits to new infrastructure until you first provide transport; toll roads, highways and even train systems have drawbacks of their own, but ideally you'll be able to build your way past those trouble spots without causing too much pollution.

When the final tile is drawn, that player finishes his turn, then everyone scores: twice for their energy and ecology levels, one for capital (with money being converted into prosperity points), once for research on both tracks (with points for those researching the most), and once for prosperity. Whoever tallies the most prosperity points wins!
