Moon Base Tycoon. (attempt to recreate a memory)

this tycoon was one of my favorite games to play in roblox untill i either forgot it's name, or the game doesn't exist anymore... i refuse to believe it but i'll try my best to recreate that tycoon. problem is that i never finished playing the original. (never bought everything or progressed more than 40% in) i'll be thankful if anyone find the real game based on what i provide here. tell me what it is in my roblox group. details: the map is giagantic. there's tunnels around it and big black buildings in the center. the tycoons are located on mountain like places at the edges of the map. there's a hidden pathway somewhere that leads to a serious of difficult parkour course (never made it to know what it rewards you.) you spawn above the map in a space ship thingy with lots of corridors leading to a tycoon claiming zone. once you claim a tycoon you get to choose a custom color for it... weird ngl there's 3 floors you can build up and a basement level. that's all i remember. :(
