I'm dating myself, but the first time I played through this game was back in the days of DOS and the original version of this game. That version had a "bug" that I quickly learned about and used. This bug allowed you to sell all of your landers and then sell again. The lander counter would then max out and you could continue selling landers. This eliminated the tedious need to find planet after planet just to earn RU. Now that this "bug" has been fixed, I find I don't have the patience to hunt for resources. I've discovered that I'm more interested in the story.
All this to say, is there an option in the game to reinstate the original "bug"?
