As far as your computer is concerned, the SSD is just another hard drive - it doesn't know the difference, and you won't know the difference using it except it will be faster; everything will still work exactly as it did before. Once you're booting from the SSD, just reconnect the other drive, go in the BIOS, and make sure the machine is set to boot off the SSD. When you get into Windows, the old drive will show up as the next available drive letter (probably D: or E: )

So the real question becomes, can THE GAME store its game files in a different location than where the program itself is installed? If so, just point that path to somewhere on the old drive. If not, you MIGHT be able to make it work with some trickery, like mounting the old drive as a folder rather than as a drive.

I just swapped an SSD into my laptop: I put it in a SATA dock, plugged that into my laptop, used Acronis TrueImage to clone the old laptop drive to the SSD, then put the SSD in the laptop. Bing, bang, boom, done.
