-Combat is similar to...well...dark souls with kill bill mixed in. DUEL hardcore (non-beta) used, on top of a couple others
-Characters/items/weapons are more like an 18+ rated anime (not hentai)
-Gameplay is more survival and hard as hell...expect to die a lot till some levels under you
-Game is definitely more sim-like (like my own overhauls I made in past)...in terms of like a business/economy style tycoon.
-Definitely very Sims like, though most of that is due to the anime overhaul
-Tons of rare mods you won't find anywhere
-My own custom mods (a couple re-textures for armor/clothing, one hair re-texture and two of my custom companions)
-A couple races only I and creator have (its abilities and effects can be used with any female race as a nice bonus)
-Nearly max mod limit WITH it being stable on my system (mostly due to SKSE memory patch)
-A couple rather unique races, 3 variations of demon race (so you can actually play a demon) and a cat-hybrid race
-Civil war overhaul used (epic gameplay overhaul) and...I'll have to test to see how main story goes
-TONS more life in the world with tons more action
-Unique lands added, new quests, new dungeons
-TONS more to explore (lots and lots of new locations, not including the new lands to find) with a whole new look to Skyrim.
-Tons of crafting options, mostly anime style stuff that was already added in anime mod
-Using the uncapper mod, pre-configured with my own settings
-Own property, fort, own a business, build your own house (build home mod, plus the hearthfire one)
-Random alternate start used (I like it a lot more than alternate start)
-Requiem used (it came with the anime overhaul, and taking it away would have made bugs)
-SKSE memory patch pre-configured and fully working, works better than SSME (SKSE memory patch is harder to get working however)
----
-SkyTWEAKS used and combat part of it is pre-configured (non-combat you'll have to adjust yourself)
-SkyAI used (you'll have to adjust yourself)
Both you can spend easily hours configuring both. Can make AI as smart, dumb, or human-like as you want...
-New lands include Shadows of Morrowind, Blackland, Wyrmstooth, Moonpath to Elsweyr, Falskaar,=
Forgotten mod names, but lands of: Hammerfell, Highrock...and there is 1 or 2 others
There is also a dungeon that is MASSIVE somewhere "sort of" close by Labyrinthian. If you go there, you can spend many many hours stuck down in the custom dungeon. In fact, one person said he was 100 hours in the dungeon and still lost and refused to reload a save outside the dungeon. Dunno if he just sucked at exploring...but...sounds cool. I haven't gone in yet. It is a well made dungeon though, and massive...but don't go there without expecting to get lost.
