Also getting back to this after a longish pause. I've always been playing vanilla so far, so this time I wanna go with a major mod. One that adds more of everything.
Can I has some recommendations here? A list, if more than one is required.
Industrial revolution: Gives you "ages" to progress through, increases complexity a bit, nice for one or two playthroughs. The good part is that it does not overwhelm you with stuff to do, and starts slow. Has this "expanded vanilla" feel. Also does not require any other mods. But FNEI is a huge QOL improvement to pass at any point.
Bob + Angel: My personal favorite. Makes the game more complex, adds tons of stuff, and most things have multiple recipes + many recipes have byproducts you can either throw away (I heavily recommend playing this with void chest mod) or use for increased efficiency. Resource mining is also overhauled, and instead of mining one ore per resource, you can process it into multiple differrent ores based upon how/ how much you decide to process it. The main point for me is that in Bob+Angel you dont need quantity as much as diversity, so it is not just copying hundreds of identical machines producing one recipe but more of dozens of different machines running dozens of different recipes. Has a research system so you dont get overwhelmed at the beginning, but in my experience the research will eventually outrun you and you will be unlocking stuff faster then you can explore it, but at the point this happens it doesnt feel like a problem. Recommended additional mods: void chest, FNEI. Oh, and I recomend not using modules, bob modules are OP. Also compatible with yuoki, and you can ignore its stuff until you feel like it.
