I'm sure this has been tossed around, but I curious to see what the consensus on this topic is.
With all the expanded base possibilities of Piratez, you really need to build new bases to take advantage of all of it. Fun facilities like the firebomb rooms and corridors combined with larger facilities makes me really wish I could build a bigger and more intricate base instead of having to be spread out with numbers of regular bases. The vanilla base size always felt fine in the design of X-Com, but it feels limiting in Piratez which provides the opportunity for so much more depth to the facilities.
