I don't know if theres a torrent for Deep powder, but there is one for 1 and 2 combined on Piratebay. From what I can gather Deep powder was some sort of DLC for 2, so I would say 2 would probably be the best choice in that case.
I always made my roller coaster without an ending and the cars would fly off and the people would die. Similar to building a fence around the pool while your Sim character was swimming, thus trapping them into it and causing them to die.
At one point I build a walk way that was really short over a deep pond. Then shot 4 different coasters into it at the same time and then delete the pathways because i was pissed they didn't blow up and let like 200 people drown. When people would complain that they were lost or that my park sucked I would drown them. When workers didn't do what I told them I would drown them. I would change the gate price to whatever the people coming in had in their pockets to build that next piece of that big ass coaster.
Then I realized that that's pretty poor business management.
Download bittorrent then download the torrent. Wait for Bittorrent to finish downloading it, then click on it and you should have the files open. Save them somewhere then click skigame.exe
