Cave Game II (r1.2.5 map + custom cave game test/Classic-style Texture Pack) -- what if Notch never made Minecraft, and it remained as Cave Game?

'Ello. I had this idea (let me know if it's already been done before, and any improvements and/or changes you may want to see in Cave Game III).

Imagine if Notch never went fully into Alpha/Beta. What would Classic and preclassic look like, down the path of his original cave game tech demo back in 2009?

Here's my best shot in Vanilla r1.2.5 using WorldPainter, trying to balance all the considerations.

Details:

1: Underground material: Cobblestone (NOT Stone, though some Stone spawn, supporting Gravel).

2: Default height limit is y=256; however, Cave Game II is intended for y=128 (a balance between the original y=64, Indev deep levels of y=256, and the Infdev through early Release of y=127).

3: Lowest standard ground level is y=62 (it's actually a bit lower due to the offset caused by the cave openings).

4: Spawn is exactly 0,0.

5: A Texture Pack exists, called CaveCraft, and is a mixture of early Minecraft and later Minecraft. But is actually limited due to lack of access to various blocks in Cave Game II.

6: World Type set to Superflat in order to remove Void Fog; this means, the default Minecraft world beyond the map is Superflat.

7: Void border around the edge of the map, 512 blocks thick.

8: Start with Starter Chest: contains 4 Oak Saplings and 4 Sugar Cane (which can be played on Grass in r1.2.5, so it's a non-issue that Sand doesn't exist.)

9: Default Game Mode: Survival.

10: Default Difficulty Mode: Peaceful. (No Hardcore Mode; most people don't play this, and if you want to, you can simply self-enforce the one life/no death rule on Hard Mode.)

11: Map format: Anvil r1.2-r1.12.

12: Map size: 5,120x5,120. (Unlikely anybody needs more space than this, even as a forever world.)

13: Dimensions: Overworld and Nether.

14: Nether terrain generation and features, etc.: default r1.2.

15: Structures (e.g. Mineshafts, Strongholds, Villages): Off.

16: Underground pockets of Lava and Water (Resources Layer used everywhere at 50% Intensity); default settings in WorldPainter export for Water (1% occurrence, and to below the Surface, but to a maximum of y=61). For Lava, I increased Occurrence from 2% to 10% (since, I believe, a fair amount of Lava/danger is more in keeping with both Notch's vision for Cave Game and its primary inspirations); this, from the WorldPainter default of y=15 to y=19.

17: Cave generation (size and shape, etc.) (I'm calling this generation 'large Swiss cheese'):

- 86% Intensity Chasms layer.
- 65% Intensity Caverns layer.

Note: This was the hardest part, and possibly the most important. I tried to balance Classic cave generation with the cave game test cave generation, and taking into account what is possible with WorldPainter (not much, sadly, in terms of default world generation). I don't love it, but it's the best I could do (unless somebody knows of better settings).

18: Ore generation, types, and rarity:

- Coal: from 10% Occurrence in WorldPainter (50% Intensity for all) to 20%; to y=128.
- Iron: from 6% Occurrence in WorldPainter to 15%; to y=68.
- Gold: from 1% Occurrence in WorldPainter to 2%; to y=38.
- Diamond: from 1% Occurrence in WorldPainter to 2%; to y=20.
- Redstone: N/A (removed)
- Lapis: N/A (removed)

Note: These figures aren't perfect, but it's what felt right when I was testing the options.

19: No Surface Water/Lava Lakes.

20: Grass top layer is populated with Flowers and Short Grass. Some of you likely didn't want this, but I thought it was reasonable to offer Flowers + Dyes, along with Seeds/Wheat. You can simply remove/discard these if you don't want to use them.

21: Biome(s): Plains.

22: Flat, single layer of Bedrock at bottom of the map.

23: Dirt and Gravel DO generate as underground deposits/Ore features; however, they're not as common (from 57% occurrence to 30% for Dirt, and 28% to 20% for Gravel); both to y=61.

24: I didn't know what to do about the Surface terrain generation, so I adhered more to cave game test than Classic: completely flat, single-layer Grass, with caves (only Chasms layer, not Caverns) exposed to the Surface. Some of you may have enjoyed a Classic world generation instead -- but I cannot recreate this very well, anyway, in WorldPainter. (If you want the Surface to be covered in Oceans, of course, you'll have to build them by hand.)

25: Top layer min and max is 3 and 7, respectively.

26: Keep steep terrain covered: On.

27: Ore blocks Stone texture changed to Cobblestone (among the other Default Texture Pack changes).

28: No vast Lava Lake level (y=10); instead, the lower part of the map is populated by Lava Source block streams, akin to Water.

29: I darkened Coal Ore block texture (the ore part) since the default wasn't very visible against the Cobblestone texture.

30: The Grass texture isn't exactly the same as the original due to certain differences in light generation, etc., which I cannot properly adjust (but maybe it's possible by hand-adjusting the greyscale Grass, or I'm just missing something).

31: Leaves aren't the same as Classic, etc., but a mixture between Classic and Beta.

32: The only changes made to r1.2.5's Items png are Coal and Flint and Steel, which use the originals.

33: In theory, you ought to be playing on Moody/the lowest Brightness (though by default, the r1.2.5 slider allows from Moody to Bright).

34: Notably, no Sand in Cave Game II. Some of you may disagree with this choice. The simple reason was, if I added Beaches/Sand, it would be much closer to what already exists with Classic. This means the Sand-based blocks cannot be made, including Glass.
