Ultimately, in regards to my previous post, I went with “The one where another layer shows up in the first row mid-game”, because I don’t remember any other trees where that happens, so that’s quite unique.
Game Page 29: Primordia (listed as “Primordia (2022)” because I had to move another game to “Primordia (2012)”) by Jacorb90. The concept is solid, I enjoyed how it relies on progression based on how much resource per second you can have and as such allows for different strategies. If this is what Profectus has in store for the future, I’m looking forward to it (pages on games made in it will currently be listed on TMT’s page until more of them are made).
