Millionaire:
A management game that used a distinctive font (vertually all games at this time used the standard font).
Lots of decision making but with a small amount of luck required if you choose the quicker but more dubious route to success. Reward comes in the shape of financial gain represented by the property you own ie from a terrace house to a mansion.
For a management game it was pleasing to the eye and provided you with enough choices to determine your future but not too many choices to make it tedious.
And there was always Honest Harry to provide an alternative route to success, if your luck was in.
