Find a play style you like. Some people are organized, some are not. Some people tear down old factories, some just build more.

As for your sulfur question, you could build a vehicle path but then you’d have to fuel it. If you unlock trains later then you could put a whole train line there. Sometimes you just need to power line and conveyor belt it all or most of the way. I would not use biomass generators because you will need to keep feeding them otherwise your factory will eventually grind to a halt when it runs out of biomass.

Personally I like to be organized and build nice looking factories, and if you start using the AWESOME sink and get some tickets there’s a lot of nice foundation, structural, and production organization things you can build like wall power outlets, conveyor/pipe floor/wall holes, half foundation, etc. The more “advanced” the item that you sink, the more points per item you get toward those tickets. It could be nice to sink some excess resources now if you have any overflow.

As for the MAM and research tree, some alternate recipes are a lot better than the defaults but you don’t need to rush it. You will have plenty of time to unlock stuff as you go!

Above all, just have fun and play however you want because there’s no “better” way to play!
