Overall, I am very happy with A21 so far. I enjoy the new new learn by reading system. The graphics are much improved and the world generation is vastly quicker than in A20. I have started 2 maps so far, 1 for each exp version. The one thing that does annoy me, espcieally with the new vehicle damagew system is the fact that the cities do not appear to be attached by major roads any longer. The new infested clears are fun and early game, very challenging with the slower weapon unlocks with this version. I have only run into 1 legacy POI that did not receive any update love so far, and that is the Don Delgado? residence.
On a personal note, I still wish there was a way to change the color of a weapon crosshair ass I make a naked mole rat seem to have 20/20 vision.
