I was rearranging a closet and came across an old CD case for the PowerPC Mac version of Freedom Force from something like 2004. I actually still have a PowerPC Mac but it's a laptop that needs a battery and a PRAM battery so it's just a closet creature at the moment. Then D'OH I remembered I have Crossover. I looked for the Windows version of the game on sale online and learned about GOG.com. (I think that GOG stands for "Good Old Games".) They had Freedom Force on sale for $1.24. That wasn't a big risk so I decided to buy it. I had to create a customer account on GOG.com then a quick transaction with Apple Pay and it was ready to download.
It's important to download the "offline backup game installer" version, not the normal GOG version. The normal GOG version includes GOG's proprietary installer/updater and I couldn't get that to work with Crossover. But the "offline backup game installer" i.e. the normal installer for the game worked with no trouble and the game functions perfectly! I was even able to go into my archived backups from the mid-two-thousandsies and found my old Freedom Force save game files. I copied them into the correct directory for saved game files...
*/CrossOver Bottles/Bottles/Freedom Force/drive_c/Program Files (x86)/Freedom Force/Data/SaveGames
...and I could pick up from any of the saves I created two decades ago! I haven't tried mods and skins yet but I imagine they'll work fine, all the needed folders and file paths for installing those things are right there in the bottle.
I'll note that I installed DirectX for Modern Games into the new bottle I created for Freedom Force before installing the game into the bottle. This probably did nothing, it's more of a habit on my part and I had done it before even really thinking about it. Since this game predates most or all of the stuff that gets installed by DirectX for Modern Games it's unlikely that it's doing anything other than taking up space. But it's not hurting anything, either.
Time to clobber some bad guys and aliens again. For freedom!
