So I'm finishing up my first epic length game at the moment, and it all went reasonably smoothly with 2 level 6 ai's (i'll probably try 7 and a realistic map next). One thing I've found is that I love scouting - searching for factories, research stations, and fabricators is the most exciting part of the early/mid game for me. I was having trouble however, even with full waves of mark 1/2/3 scouts (maybe 35 scouts to a group) - I couldn't scout anything past 2 or 3 jumps out, because the AI had tachyon guardians at pretty much every warpgate (I'm not sure if this is something specific to a certain AI type, I chose random easier).
Then I found my first advanced factory and built my single mark IV scout, which I provided to send all over the galaxy, uncovering the entire map without a hitch! To be honest, I'd prioritise the factory highly even if that scout was all it provided me. Being able to find all the targets of interest, including the homeworlds, relatively early on, let me really strategise about where to take territory.
So I guess the purpose of this thread is to express my great appreciation for the capabilities of the mark IV scout! but also to ask if it's unusual to have such a hard time without it?
