Wabbajack is a mod organizer / installer that lets you load mod orders that have been configured by people who borderline make Mod Orders for a living. I cannot stress enough how much they took the thinking out of modding Bethesda games.
Pay for a 1 month sub to nexus mods and set the installer to run overnight.
Can confirm, Grimrock 1 and 2 are super tight. Extremely true to their inspiration while modernizing basically everything. Slower, Not a slog. Tough, Not cruel.
