Not interested in mods really. If you know some fantasy mod for Minecraft, that either fits the base game well, or is a total conversion, then i might be interested.
With meaningful goal, merely adding stuff to the game is not interesting in the least.
Besides, i was talking about the base game and what's wrong with it.
Also, not interested in difficult gameplay in itself, but rather survival should be fun and meaningful. This is a major issue in many survival mods for various games, they're tedious (or their understanding of difficult is "tedious") but not fun in any way, or even meaningful due to lacking an ultimate goal. Making survival itself a complicated process diverts too much time from other elements of the game.
And i don't find making the tech progression difficult interesting or fun, something the both mods you suggested seem to do*. It doesn't make building stuff important. Most likely this "Dig a hole into ground and plug it" survival still works, ignoring hunger.
Let me build a castle and defend it at night, get stuff during days. Make me build big structures, make me defend villages and build villages. Give me reason to look for diamonds (i don't usually bother doing that in MC, obsidian i make with lava and water...). Give me some reasonable goal to work toward.
*How come MC modders can't be make a good, simple but comprehensive description of their mods? Too often i see a couple of sentences at most and "Experience it yourself", i rarely get a good picture of what the mod(pack) actually does. And listing components of the pack doesn't help either.
EDIT don't get me wrong, the sandbox aspect of Minecraft is great... for multiplayer, where building stuff for yourself and others to see is enough. For single player, i want some tangible reason to play.
EDIT also having a goal doesn't mean it is A-to-B gameplay, if the player can choose how to do it.
EDIT as for building stuff, it is irrelevant in single player, as i can show-off in multiplayer much better. Or i could just build something from legos IRL. MC multiplayer is fine as it is, though "well enough" is not "good"... MC single player is what bothers me.
