Yes, I know! Hence the "If"... :-)

Yes, even now, if I started a 3D game, I wouldn't bother with software
rendering, as by the time the game is finished, everyone that would want
that game would have a 3D card.
But for intrinsically 2D games, they can be run on very lowly hardware.
For example, Quadra on most 486 is fine, if you stay in 8 bits
PseudoColor (I use a 16 bits TrueColor visual on my 486DX4/120 without
too much trouble, only the fades between screens are very slow).
Insisting for an expensive 3D card for a game that could work on a
low-end machine with a cheapo 2D card is not a good idea IMHO!
