I went into Tekkit The Resurrection 2 wanting an experience where I could create automation using mods that required a small amount of engineering, but once in game, the most efficient (and most boring) way to progress is through ProjectE. This mod makes progression FAR too easy and honestly ruins any semblance of difficulty. You mine for the first 20 minutes, then you have access to everything you could want for the rest of the game. You play in creative from that point forward. There is no automation through engineering, there is only ProjectE. If you want to play creative Tekkit, this is the pack for you, but I simply cannot recommend this due to my own bias and enjoyment from video games.
