Alhambra: The Red Palace

From BoardGameGeek:

The Red Palace is a standalone game set in the Alhambra Universe that provides a new style of gameplay and is designed specifically for more complexity in the base game. It features: The (3D wooden) buildings and walls are now separated. Guards as a new mechanic, which make choosing and constructing buildings more exciting and introduce new powerful extra actions that might bring you closer to victory! Each player constructs their own Alhambra by taking money cards and using these to purchase buildings of different types. Which buildings you can build are displayed on the building market. Unlike the base game of Alhambra, the buildings are not printed on the tiles, but instead players draw a tile and then a chip which tells them which of the wooden buildings is placed onto the tile. In each of the three scoring rounds, players will receive points if they have the most of each building type, as well as points for their longest connected wall segment. When buying a tile, players check for guard icons on the walls, placing one guard on each icon. The guards do two things: Guards standing on your longest wall give you bonus points during scoring. They can be discarded to do powerful extra actions during your turn. The game ends when the building market can no longer be replenished from the building tile supply, and there is a final scoring, whereupon the player with the highest score wins. Note: All existing expansions for Alhambra can be added to Red Palace. For the tile based expansions, if you have the Mega Box, you need the Deluxe Edition as it has the 50mm tiles instead of the standard 45mm ones.
