I’ve played some more Zak McKracken and made some more progress. But this required going back to previous save files or some tedious travelling because his funds ran out. And when I wanted to make some more progress, my way to the Bermuda Triangle was blocked because there was no plane. This caused me to gave up.
But there’s already a new challenger waiting in the form of Indiana Jones and the Last Crusade. I noticed that Atari St games are a lot cheaper than Commodore games, so when I saw this game on offer for much less then what the Amiga version would cost, I didn’t hesitate. I’m going to play the ST version through ScummVM on my retro computer setup.
