Going back into the world of Skyrim again, but with a crap ton of mods. Using Climates of Tamriel, a custom ENB, and the official high res texture pack makes the game look more like a high res fantasy game. It looks fantastic (only a loss of 2 fps), but I will be switching back to realistic lighting once it updates to 4.0.
The Monster Mod (I had V6) has been updated to V9 and the new creatures can be somewhat scary when enter a dungeon (climates of tamriel also affects indoors so dungeons are darker). At least there's variety now instead of bandits, draugr, or falmer. Also, immersive armors, jaysus swords, and morrowind/oblivion weapons and armor just adds even more reason to explore the dark dungeons again.
SkyRe makes the game even more challenging. I love it! Deadly combat, balanced magic, thief tools, magic duels, apocalypse spells, phendrix spells of witchcraft and sorcery, and deadly dragons make the combat a hell of a lot more fun! UFO is also a must if you want even more companions.
The newest mod that I'm getting into right is Interesting NPC's. It adds about 90+ npc into the world of Skyrim, but they all have a pretty cool backstory. It also adds a couple new dungeons and quests as well.
Guys, get this game on the pc!
