This is not really game changing in any way. But in GC2, one thing I always enjoyed about it, was when you researched a new tech, you got that automated guy making wise cracks about it, like "Now the laiens working in our warehouses REALLY are aliens! Get it?" That stuff. Can you make a point of having that included and expanded on, it always cracked me up, the dry/silly humorjust fit into the game so well. Serious thinking game, that has stuff that still makes you laugh, doesnt get better than that.
THIS IS SETI ALPHA 5!! As a planet type description in your GC2 manualk 
Please stay with that, it was minor, but I loved it!
