Played a little bit of 18.3. I liked 18.3, but it was still not as good as 16. I would like to say I was very disappointed in 17 and 18 is a step in the right direction. However, Alpha 16 was an almost perfect game. All we needed were some bigger bosses that could do more damage to bases. It seemed the difficulty leveled out after a certain point. Rather than fixing those small issues, the developers gave the game an entire facelift.
