What responsibility do you feel this person has to you to spend money to validate this in the specific way you would prefer? > Not really, when you do CD releases you have a "gold master" This is an oversimplification. In the late 90s / early 00s when 3D APIs were more fragmented than they are today, many games had different releases built to support different GPUs. There's also versions distributed with hardware that include checks that the PC contains the specific hardware. MC2 had separate NA and EU releases, there is at least the chance of multiple versions from internationalization.
