By the way, for the IIgs versions, Sierra added (cheesy) digitized SFX and some decent midi music. The IIgs has what are considered to be the best AGI ports, though 160x200 graphics kinda hurt to look at.
BTW, Ken and Roberta said the IIgs "wasn't powerful enough" to do Sierra's SCI engine and totally dumped support. Yeah, 320x200 graphics at 16 colors is real fuckin' hard to do, especially when some of the best GS programmers around were telling Sierra that they'd do it FOR them for a cutrate price. IDIOTS! GOSH!
