I thought some of you would like to know how we came to publish
Railroad Tycoon Deluxe.
Our Japanese development group released Railroad Tycoon in November of 1991. The game was a direct port to the NEC 9801 from the IBM. Our Japanese customers looked at the EGA graphics and said "Uggh!" or the Japanese equivalent.
This motivated us to rework the graphics system for a 640x400 16 color graphics mode, (NEC Format.)
In the process of reworking the graphics, we decided to add new
theaters and trains. After we released the Japanese version of the game we were asked if we could release this product for the US/UK.
Because of the interest we had on the BBS's we decided to include it in our Spring 1993 release.
We have concentrated on new worlds and economies and a sound and art upgrade. I have read your posts.
