It's NOT the most accessible mod out there (think Botania or Gregtech, not ProjectE or Thermal Expansion), but if you're a nerd that likes making Rube Goldberg machines and/or war crimes, there's a good chance Crossroads will be up your alley!
Over the years it has evolved and grown so much from its initial release, yet it's retained the complex yet rewarding, nuanced but silly nature that made me love it in the first place. I'm certainly biased as one of the oldest playtesters sorry for getting so many things nerfed! but while I can't describe it in a way that does it justice, I STRONGLY encourage players to give Crossroads a try =)
