Games below are believed to be SCUMM based games... most haven't been proven however. Every title Humongous Entertainment released before Backyard Hockey (early 2002) should be SCUMM based. Mac versions not listed in the interest of space, they seem to be the same as pc ones after you rename certain files anyway. Besides anyone who has a mac version has a PC version as the games are on hybrid HFS/ISO9660 CDs.
