Why are people recommending 3D games like Quake 3 or PrBoomGL for a Sam460? They won't run unless a Radeon 9250 is installed, and as far as I am aware no Sam460s ship with that graphics card (yeah, I know it's kinda daft, if only the PCI slot wasn't taken up by a SATA card).
Side note: "Software 3D" games like Quake 1, Payback or Freespace should work. But anything using Warp3D or MiniGL won't, at least until AmigaOS4.2.
