Welcome on board Jas!
Could you tell us what was the name of the file? (especially the extension)

If the game ended with .zip , .rar , .ace , .tar , .tgz, .tar.gz , .bz , .z7 or... Then you do really need to extract it first. win ace is indeed a tool to extract archives, but you do need an emulator program to play it, in case it is made for emulator (if it is so called rom). Monte is right, for amiga roms winUAE is a decent emulator

Although selecting correct kickstarts & configurations may be a pain..

Well, feel free to ask if you encounter problems, I am quite sure heres certain members who can really help you

(I myself am no master with emulators either)
Just a tip how to increase the propability of getting a good answer:
Be as specific as you can. Tell exactly what did you try, and how did it work.
Tell exact name of files, and programs you used.
Also if you ever have problems with running old PC games, it is a must to tell at least
1. what operating system you used
2. How old/new computer you're running, or even better, the speed of computer, amount of memory, graphics card type etc...
Anyways, for the behalf of the whole crew & community, I welcome you and wish you'll have a pleasant journey
