The $64k question! The very first title on the list f. e., Falcon 3.0, only requires it for the "hi-fi" flight model. Quake certainly needs an FPU. Don't know about the others.
So or so, the info needs to be verified for accuracy, e. g. if a 486DX-specced title really needed (or profited from the the presence of) an FPU, or if was just a speed requirement/recommendation. And some of the game covers's spec boxes don't mention anything about an FPU at all. Etc.
