I've had a retail copy of RollerCoaster Tycoon 3 since it first came out, which was several years ago. It's a great game. I don't play it as regularly as other games, but I still love it.

The other day there was a Steam Daily Deal on RCT3: Platinum (RCT3 + Soaked! + Wild!). I went ahead and grabbed a copy because I don't have the expansions, there was no way to purchase each individual expansion via Steam, and 10 bucks seemed a good deal in my book anyway. Also, I like the Steam platform.

My save games and other data are probably going to be compatible two expansions up, so I'm not worried about those, but what do I do with my existing RCT3 installation itself? Do I need to get rid of that first before having Steam install RCT3: Platinum?

  • I realize Steam installs games in the steamapps folder, but I'm not sure if any unexpected conflicts are going to happen, so I thought I'd stop by and see if anyone knows better.

You should run into no problems. If you're hurting for disk space, you could delete it, but your OS knows which one is which and they are not sharing resources.
