Cube World - Cut/Planned/Teased content that was advertised

No Mac compatibility, no console release, no new classes, no new playable races, no advanced skill trees, no building/decorating your own house, gliders now punish you by stunning you more than 10 times as often as they did in alpha, climbing is nowhere near as fluid and intuitive as it used to be, often even when you land at a pretty much flat angle on entirely flat ground, nothing exists at the bottom of bodies of water anymore making them lifeless and pointless to "explore," no more giant pyramid dungeons in jungle biomes, there's no longer any system in the entire game that allows you to choose how your character progresses such as the specific skill leveling system the alpha, no pirates on boats (only dry land. Makes sense, right?), none of the planned boss monsters, no capital cities, no ability to join any of the factions...

No more choosing your own world seed to explore unique, interesting areas since the world now uses the same seed every time which infinitely loops the exact same types and shapes of biomes in the exact same order in all directions after awhile (great game design!), LAN multiplayer is no longer possible, roads now always lead nowhere instead of being guaranteed to lead to/from a point of interest and can no longer cut through mountains making interesting, comfy tunnels, alpha had cool guild halls for all the different classes - rogues had a dojo, warriors had a sentry tower, rangers had an archery range, and mages had a training den with dummies and bookcases - but Wollay decided that we can't have nice things so he removed them all and replaced them with a grossly generic building called "The Guild," crossbows no longer drop for some unexplained reason, they can only be crafted (and crafted items almost always have worse stats than quest drop items)...

No PvP, no PvP online ladders, when you die you no longer respawn near where you died to allow you to get back to what you were doing at a reasonable pace; now you nearly always respawn miles away, usually forcing you to tediously waste massive amounts of time slogging your way back to where you were & what you were doing each time you die, no more spirit cubes (which would've mostly fixed the broken region locking system - your gear would lose its stats but you'd keep your spirit cubes; that theoretical system would've allowed players to progress at a steady, but not overpowered, rate), no race-specific headgear, no vanity items, no experimental massive servers, no savanna biome, no undead biome without vegetation, no mushroom biome with huge insects, no coherent, in-game story that you can experience from start to finish, no rare pets, no pet evolution...
