This was going to be my answer - I probably put over 500 hours into Terran Conflict in a single playthrough.PacDwell said:X3 (either Terran Conflict or Albion Prelude) are huge time sinks once you 'get into them'.
Starting off can be slow but, by Christ, they can evolve into something you'll play for days without sleeping.
I remeber how pleased with myself I was the first time I designed a complex that produced microchips and silicon wafers without me having to do ANYTHING to it - apart from an initial injection of energy cells.
Designing self sufficient complexes like that are when you start being able to truly create an empire.
Now - where's my fleet of capital ships?
