Right now I'm working on a light space colonisation game and I need a good idea on how to make a deck of structure cards and a fixed tech tree (its drawn on the game board) connected. Naturally, I want people to only be able to build structures they already got the tech for but also I want only few of the structure cards visible at a time and as the players progress in the tech tree they'd have more advanced structures available.
If anyone has played Through the Ages, that might be the kind of system Im aiming for but not quite. The problem is, that if I make the structure cards change as fast as in TtA then players might face a situation where they dont have the tech for a certain structure before its already discarded. So I need the card row to be somehow connected to the tech tree.
I had an idea that the cards available would only be discarded or drawn when a player invents a new technology, so that the cards would come and go as players progress in the technology tree. But then I became to wonder if this would make the tech tree too restricted as I would have to connect many of the technologies together so that right cards would become available when right technologies are invented. And would this harm players who are left behind in technology since they wont have those low tech cards available when they cannot build the high tech.
Im not planning on implementing any kind of "action point" system into the game so that is most likely not an option either. Of course the row could move like in TtA and the players could buy the cards for their resource cost into their hands before they got the tech and later build them to their colonies but Id really want to have a more original idea. Would be nice if somebody wants to help me brainstorm.
Theres a card row in the middle of the board that represents both the flow of time and the available technologies and structures. Every turn players use action points to draw those cards into their hands, the leftmost cards cost only 1 action point whereas the cards further away to the right cost more points all the way to 3. As players draw cards, the row is moved forward so that there are no gaps between the cards, then the 2 leftmost cards are discarded and the row is moved again and the empty spots on the right are filled with new cards. The row moves pretty fast so IMO this system can easily ruin somebodys came because they just dont have the chance to get the cards they need.
