Dark Forces strikes me as an odd choice, since at that time period, LucasArts had in-house Mac porting developers. Dark Forces, Loom, and even Sam & Mac got classic Mac OS ports that supported better graphics resolutions than the DOS games of that time period. Pity it was mostly based on the work of one key developer who moved on after a couple of years…
