First part: impressions as general as I could(3 min in Paraleo time), the production changes which the old player base doesn't seem to like that it is too Frostpunky right now, I didn't cover that topic, but they do have some new interactions between factories which might increase the need of thinking very well before placing them.
In the second part Expeditions which is my favorite change in Endzone 2.
From a visual standpoint, I didn't realize I had sharpen on, also the default for the textures is set to low so that is why some players may think the textures are bad compared to the original I think.
