Actually, if you speak with the nords in Solstheim, they tell you upfront that those zombies are a complete abomination and are not protectors. The Skaal despise them for being a complete mockery of the All-Maker, and the guys at Thirsk hate encountering them, because they're zombies with the bloodthirst of a beserker. Here's the complete dialog offered by NPCs in BM of what they think of the draugr (the nord zombies):
Thanks for that. It seems I had it a bit missmatched for some reason.
The point of being a lich is so that your mortal shell is now a corpse that'll no longer give up on you, so you longer die a normal death. Basically, it is completely intended that when one wants to become a lich, they want to be a magically powerful undead being. Think of it almost like an immortal shell for the soul to remain in. Plus, in every freaking game, they are either skeletons or corpses with immense magical power.
Well, the fact that in every freaking game they are shown somehow does not mean that they will be like that in TES as well. I do not know about you, but I kind of like it that Beth sort of change many of the given rules and they try to be original.
And as far as the look of the lich goes, I understand it that after the process, your body is dead and thus is suspect to decay. But just after the process, you could look unhealthy, pale and whatnot, then after some days your flash would begin to rot and fall off and after some time you would be just a skeleton. What I'm saying is that the skeletal look does not have to kick in right after the ritual. Sure you will end up like that, but it is like aging. Your avatar in TES games will get older eventually, but in the course of the game you do not see any changes.
Ok sounds ok I guess... but I say no unless you can give me some good reason just because this just sounds like something you would have to do if you were bored, because you said you wont be able to talk to people, people will hunt you, you basically cant go into cities cause guards are hostile, and you cant do certain quests. Sounds like fun...
And the perks mostly sound like a well off mage. (except for the new faction and undead wont attack you)
In Morrowind vampires worked that way. And for thousands time, the fact that you would be attacked on sight and unable to start a conversation with any NPC is just your unfounded presumption.
Orcs, khajits and argonians are accepted races of Tamriel. Liches are undead beings that ,unless summoned and controlled by someone, are hated and will most likely be attacked on sight or fleed from. Now if liches are accepted by the communities why aren't there any walking around on the streets, buying things, having conversations and such? they are simply not welcome to the cities and villages. All liches that we have seen are rotten corpses that are hiding inside caves or tomb, no lich is walking around like a common person and thats why I assume all liches are rotten corpses.
Now if liches are playable shouldn't ghosts, zombies and mummies be playable as well?
Attacked on sight IF RECOGNISED. Besides, the Empire is big and the cultures differ. The approach in the parts of the Empire we have already seen may differ to those we are to see in TES V.
Especially in TES IV liches are not handeled well. But neither are vampires, bandits or other groups. Besides, it is very well possible that there are several ways to become a lich or that not all the liches are the same. Look at vampires. The first vampire was created by Molag Bal. And now, they are all very different as described in that Oblivion book, so why would all the liches have to be the same.
And as far as playable skeletons, mummies and zombies go, I do not think that this is possible. There are proves in the game that a lich remains his personality and self-awareness, but so far it seems that zombies, mummies and skeletons are mindless, therefore hardly playable. With hosts, it is more difficult. Some evidence suggest that a ghost can retain its former self, but they usually stay in this plane of existence for a singular purpose and sometimes are unable to manipulate the world around them other then by words or hints, which would strongly affect their possibilities.
