To me, the best representation of Sevtech is that Endermen begin spawning after you already have to have built a smeltery in the game's progression, and have been tweaked to drop ender dust, rather than ender pearls. Ender dust can be put into a smeltery to melt into molten enter, which can then be cast into an ender pearl.
Why?
For what purpose?
It would have been easier for the developer not to change the enderman's drop.
It would have been easier for the player to not have to do these extra steps.
It would not change progression if endermen dropped ender pearls.
Why would anyone have done this?
What thoughts must have been going through the mind of Sevtech's creator to have ended up wasting the player's time like this for actually no reason?
Too few modpacks have a clear and singular vision the way that Sevtech does - It's beautiful, I love to see it, I hope more modpacks aspire to this level, and I hope that the singular vision they have is better.
One thing that stands out, with Sevtech, is just how little it cares about your time. Darkosto really looked at the thing in vanilla where you put your stuff in the Furnace and go read a book or something while your computer's running and said "that's amazing, I want that!"
Because progression is largely in a straight line, rather than giving you several things to do at once, I often found myself in the position of, say, needing Buffalo teeth to make the next piece of tech, and waiting around for my buffalo to breed, then grow up, then breed again, until I could afford to lose a few, or starting up a coke oven and needing two stacks of steel or three arc furnace electrodes to do the next thing in the list, so just having to wait for it to slowly process stacks of coal.
The Geolosys ore clusters are an interesting feature, but because they replace vanilla ores, rather than supplementing them, this was a minecraft where you don't really go mining, which I can't say is really what I come to MINEcraft for.
Now, these things were not what made me give up the pack, that was forcing me to interact with Pneumaticraft, even I have limits, but make no mistake - there was good stuff on the way there.
The amount of work put into this pack is mind-blowing, so much stuff that no other pack would dare to tweak is configured, even mods that have practically zero actual documentation, which I don't understand how Sev themself managed to configure, but looking in this pack's configs for examples is pretty much the only way that other modpacks make use of these mods.
Sevtech is supremely annoying in its insistence that you deal with mods like Pneumaticraft, Abyssalcraft, and Primalcore, it redesigns huge swaths of the game into something unified and interesting, with all kinds of reworked recipes, and yet still suffers from that kitchen-sink pack thing where non-vanilla resources are worthless. Primalcore fills the nether and end with plant fibers and clay variants, and they're not good for anything whatsoever.
Idk where to fit into the review that Primaltech is really cool and I love using it.
In spite of everything, Sevtech is a really impressive showcase of what modded MC can be and do, and I love to feel like I'm experiencing a creative person's unfiltered vision, even if that vision is practically the opposite of what my own would be.
