you're right , steam is easy to get . lava is easier to get. i do enjoy lava filled piles but playing with the same power generation over and over is just boring.
and i uninstalled railcraft because is pretty much useless if you have immersive engineering.
boilers are the only reason i had railcraft installed and the iron and steel tanks. but i can use the boiler from MFR for steam and i can use portable tanks from other mods eliminating the amount of resources i need for the tanks ,
i edited my lava fabricator to fit my playing style currently is harder to make requires more resources etc end game stuff but i upgraded the amount of lava you get from it and lowered the tick rate.
i have a bigreactor small 3x3x3 reactor generating power straight for the lava fabricator. steam i use it for end game.
steam dynamos are a good starting source of power.
I don't know about you but i don't enjoy using the same mods over and over on each of my worlds , think about it you and you probably already planning on making a pulverizer and a redstone furnance or a grindstone before that. am i right? either that or sag mill with alloy smelter but not me i want to give a chance to all the mods i have installed. Back in the days that i didn't care i had mods installed that i never touched for a whole series.
just like forestry multifarms , i rather use those than MFR planter and harvester. more fun more resources not simple and complexity. but that's just my style of gaming. i don't like stuff given to me that easily i disabled all my pickaxes only wood then next tier would be quartz from enderio then iron then diamond. no swords except for iron or diamond. i made planks give 2 stick rather than 4 and 2 wood from 1log. i like minecraft the survival way
but is on how minecraft suit you the best.
