So I have been playing around with game, even played an AI game to get a better handle on the tech tree and the ship improvement process on cakewalk levels. I researched all the weapon techs but for some reason no ships other than beam weapons based ships get built out, for example once I research the small hulls, only the phoenix and defender gets built out despite I have completed the prerequisites for the missile (so no cruisers) and mass driver (and no thunders). I also noticed that not all beam ships get built out too for the other hull classes.
The other thing is that even if I add an engine, I see no improvement in the distance being travelled.
I am wondering if this is because I am playing a customized race and/or I am playing a cakewalk level game.
Any advice you give would be greatly appreciated.
