If you missed it earlier this year, Phil Iwaniuk's mod-driven quest for photorealism in Skyrim is a great read and its practices are a guaranteed way to get more from the fifth Elder Scrolls instalment. Conversely, adding Batman to Skyrim Special Edition is great fun too. 

As this mod's name suggests, the latter is exactly what TuffMcKagan and Doc117's The Batman in Skyrim is all about.
