Zoo Tycoon retail Complete Collection (PC/2003) inside box (w/ Rollercoaster Tycoon 2)

Product Name: Zoo Tycoon retail Complete Collection (PC/2003) inside box (w/ Rollercoaster Tycoon 2)
Was purchased pre-owned, but in good condition. First disc shown is the retail original Zoo Tycoon game. Second disc shown has the expansions packs: Dinosaur Digs & Marine Mania The third disc is the Rollercoaster Tycoon 2 game. I installed Zoo Tycoon & the expansions on my old desktop computer, but did not play it; I know it runs. Box still contains booklet for Zoo Tycoon, as pictured. Rollercoaster Tycoon 2 was included when I purchased Zoo Tycoon, but I never tried to run it. ***PLEASE*** check system requirements for either/both game(s) before purchasing!.
