unfortunately, the development of minecraft made this even worse.
first off, beds were added: you no longer had to play during the survival section, which removed a great deal of the drive to play.
feel free to play in hardcore permadeath mode. me, i like resetting my spawn location to the last bed i slept in.
crouching was added meaning you would never again fall into a blob of lava(about 99% of player death).
yeah, never happens. sure.
sprinting was added meaning you could just run away from whatever trouble you put yourself in.
oh no, the ability to move a bit faster than normal for a short time if you aren't starving! screw this game!
food was changed to become stackable, meaning you no longer had to juggle the risk between inventory space and survival ability.
a total of 36 inventory slots, 9 of which are the hotbar. you can easily find yourself overflowing.
magic made you even more powerful (and the game a lot sillier)
the only magic is item enchanting, exchanging xp for item upgrades. they aren't so powerful as to make you invulnerable. mobs can also sport upgraded gear.
world generation was changed (so many times) removing many of the fantastic vistas you would get in minecraft.
in short, the best ever survival game was made so that the easist thing there was to do, was survive. surviving in minecraft became so trivial, that there was no challenge to it whatsoever.
mob AI was never made any better
(wrong). game advancement was never implemented (there was much talk about mobs which will eventually - meaning "some days after spawn, thus implying increasing difficulty - come and dig out your house, forcing you to build better defences), and after a while the only "improvements" that got added were purely aesthetic
(no idea what you're on about there).
it was sad seeing the game getting gimped at every turn. fire being made almost harmless
(wrong). zombies no longer falling on your head from above
(wrong). coal being changed from the single most important item in the game to something trivial (as you can just make charcoal from trees, an infinitely renewable substance which requires you to do zero exploration at all)
(you can explore and mine as much or as little as you like). the famous minecart physics bug was fixed meaning no more rollercoasters
(wrong). monsters no longer suddenly spawning in dark areas if you are close
(wrong). fall damage was made smaller
(wrong). player reach was made longer
(i can find no evidence of that). and so on and so on.
ofc you could always play infdev and pretend there's an update around the corner.
either that, or IndustrialCraft2. or TerraFirmaCraft.
