out4space: Heya,
sorry late reply.
The game has no scenarios.
The game is loaded via Dosbox and opens with a selection screen (select "1" to play the game).
The Intro starts, which you can skip by pressing any key, than the main screen appears.
Press Enter on the main screen and type in a "profile" name.
You need to do that every time, because this profile will save your progress and savefiles.
Note: a typo with your profile name, will end up starting a new profile. You would need to exit the game and restart it, than "log in" again with your correct name again! Next select "start new park" on top,folloed by a new selection screen with different game parameters.
Make your selections and than click on the checkmark.
A worldmap appears, there select the highlighted symbol.
Press "buy land", again select the checkmark, now you should be in the park view... enjoy.
