Yes, but Half-Life was designed to be somewhat playable with software rendering even on a 133MHz Pentium and that would have been the better rendering path on the earliest iMacs. In my opinion in that generation Half-Life's software renderer looked better than most of those cards due to the blurry textures and poor scaling (lack of VRAM basically unless you had cash for the 32MB versions) so no big loss for single player play.
