7 Days to die in alpha 16 vs what we have now are almost two completely different games. They are so different in everything you could almost sell them as separate games.
We dont have learn by doing, we dont have a proper weather system, we lost the customization with characters that we had back then, we lost clothing options, cant get warm near campfires, the desert isnt hot, the snow biome isnt cold, you cant get wet from rain or going into a pool. Thats what we lost from alpha 16. Hell we dont even have a temperature system so how the heck do we even get hot or cold? Lol
What we have now are magic potions that negate hot, cold or radiation debuff. You kill zombies and gain exp to get skill points to do more damage instead of you know using the weapons you want to get better at so you do more damage woth them by learning to use them.
This game especially after the 2.0 update has become a linear RPG with some open world mechanics. Its full of dungeons, quests you need to do, a leveling system, a class system and magic potions. Quests which you have to do in order if you want to go into other biomes and live in them.
Like I said I can't go into whatever biome I want anymore unless I do a quest in a certain order or turn off all the content update which is dumb. If I have to remove more than a year of work from the dev team to make this game into a open world sandbox they screwed up and released a bad update.
