Finding the game from amoung dozens of boxes of things would be a long chore. Possibly someone else on the forum can provide the manufacturer ? It was for the Amiga.
Star Flight II synopsis - Using the original ship and a single lander, you visit planets to collect organics (plants and animals) and minerals. There are aliens everywhere and most inhabited planets have several trading Posts. In a trading post you can buy what is locally worthless and sell what is locally valued. The traders always are willing to haggle. Once you have visited many inhabited planets noting the trades available on each, you will discover that enormous profits are possible without anyone being cheated simply by following crafty trade routes. I will not spoil the tale by giving the ending, which has a surprise twist.
Other games I found during a brief rummage :
Battle Isle - UBI SOFT - Blue Byte - mostly tactics
The Colony - Mindscape Inc - 3d shoot em up rescue mystery
Using Amiga Intuition games can be developed in a fraction of the normal time....
