Space Quest IV:Roger Wilco and the Time Rippers (1991)
This game was the turn of the century for the SQ universe. I dropped the text parser and put in cursor control,it has an all new 256-color palette, and it started gaming with CD ROM's and talkies. The story line goes like this: Roger's son from the future sends Roger to the future to stop Sludge Vohaul from taking over Xenon and eventually taking over the universe. This is a game I have played at least 20 times.
