Alpha 17, despite some of it's positives was a huge let down in game play for me. Being mainly a melee guy, the new mechanic was torture to learn, and was too precise (pin point accuracy with a blunt weapon). The skills tree was bethesda boring and uninspired. I didn't care for that at all. And the stamina drain was a thing of hatred.
I tried to enjoy it, but it was to me the most boring game play since I started in Alpha 11. So I quit playing, i started again with some mods, Khaine's Mod kept me going for quite some time and added back a lot of the fun the pimps stripped away. But the boring small flat maps weren't much fun to explore.
But that only lasted for a while, the game still had something missing that previous alphas had.
Alpha 18, much much improved over 17 as far as I'm concerned, however outside of getting infected on the first day and going through 2 massive hospitals and countless buildings and not finding an antibiotic, only to finally find enough to cure me in the huge shamway warehouse complex, I've been pretty bored. And the rng maps, while more variation in height which is nice, are far to small and not much fun to explore or loot. And I think the dungeon Poi's get a bit stale to loot to quickly. It's great there is so many, but it almost takes to long especially if you're looking for one specific item like honey or antibiotics when you're infected.... Although that mechanic is SO much more fun than the a17 version which I despised. It's more like the early alphas with it's stages.
I couldn't stop playing in alpha 11 -16, well to be fair in 16 I did stop a few months before 17 came out because I didn't want to start over when we all thought the new alpha was just around the corner. but then month ticked away month
I'm happy people are enjoying it, I'm glad there is older versions for those that wish to go back. I just find the game is less interesting and I find I can make up an excuse not to play or start again when before it was such a huge draw, Always something I wanted to do to improve the base, or change or find, or finish leveling.
Something about the game play has soured my experience and it isn't as fun or enjoyable as it used to be. For me at least. I don't like the specific item parts (steel tool parts, bat parts? seriously? it's a bat) but I'm sure that can get modded out.
And the getting diarrhea from boiled water did frustrate me as it happened 4 times out of 7 drinks the first day I played. Of course learning you don't drink boiled water and after that it wasn't an issue any more. but still to me that's a goofy mechanic. I can see some arguments make sense for that, but yeah...
Also stack sizes need fixing. Add a bottle for pills, 10 pills in a stack?? I mean that would just sit at the bottom of your pocket and not take up any real room. but yes, of course no way I'm carrying a stack of 500 flagstone blocks either
but anywho, enjoy it, don't, complain for a bit, and play something else until it feels more balanced and fun.
PS
I forgot to mention zombie ai, I believe this is one of the main detractors of the enjoyment. It's to predictable and simple to cheat. But at the same time if you don't they all attack one block which makes it lame too. I like dumb zombies, I've always enjoyed the dumb zombie movies, Always could point out what I would do to stop their progress in a movie (or in the walking dead which come on, some dumb decisions in that show - read the comic it's better

) but now, they are too smart for their own good and it hurts the game for me.
