I would have liked to see the terraforming in action. In the beginning, it took me a huge amount of hours to get to the terraforming. (took me at first many days). Now I can do it in 2 or 3 hours.
The game always crashed when reaching that stage, or started to behave in many weird ways, having the interface freezing or changing colors and many odd stuff, including losing yor game data of being unable to save...
I really like seing that video animation of the small plane flying over the planet. But there was nothing else thereafter.
Clearly the game wasn't meant to reach that stade or they didn't care finishing the game to that stage, since it is too long to get there. I serached many times in the ressource files of the game and found a blue planet image, with clouds and clearly an atmosphere. When I discovered that there was such a planet, I started all the possible missions/solar-systems/planets, in case that you could land on that peculiar earth-like planet.
That never happened. Outpost 1 is incomplete in many ways. You could either end up launching a new spaceship (which was complete), or either terraform your planet and live for ever on it. (that could not be completed).
That could not be completed because it's the laws of physics that dictate that; a small computer (especially those of 1993) can't handle all the possibilities of a permanently evolving empiric universe. And Outpost 1 was really complete in that sense, since you had an infinity of configurations possible.
I loved trying new ways of interconnecting my buildings. I was at school drawing schemes of cities on squared sheets. Trying to create the most optimal distribution of buildings, in search of the ultimal ratio of Buildings/Tubing. Where I named buildings by code letters and imagined my city level by level.
I would have like to see real railways and trucking/highways, which were pretty useless in their current implementation, and that are still missing in Op2.
Op1 had a really deep search tree, including social science, psychology, ecology, medecine, materials, energy productions, and so many topics that made the game really complete.
I also really like the "Fundamental research" that was never complete. You could always spend time on that research and it increased the global level of knowledge and technology. That is also missing in Op2. It could be a continual "Productivity Engineering" that exists in Op2.
In brief, Op1 gave me a lot of good times.
