Okay, since I had so many medieval rpgs and other such builds that I have worked on and have later abandoned, I decided to post them all in a sort of mega-topic.
So, here they are, in no particular order:
Dark Days
Dark days was a steampunk style rpg with a major focus on travel between areas on ships and airships and such, anyone who has played acerous(?) rpg will know what the system was going to be like. I really didn't get far with this at all, and it was really just the intro part. (You would be teleported to various areas and would see a sort of scene in each one which would describe the beginning of the rpg.
Pics:

This was the first scene, in which you attempt to steal a magical orb from the office of a well known explorer that you would sell on the black market.

This is the second scene in which you are teleported into an alley way after being chased down it by a cop, who tranquilizes you and brings you to the third scene...

In a court room where you are convicted of stealing and planned fraud, and are banished from the country. There was more to this, a mini ship that gets hit by lightning after which you wake up on an island which serves as the tutorial. I didn't think the boat was very good though, so I decided not to post it.
Fallen Earth
(Yes I know there's an mmo with the same name)
This was mainly story based, at least at the beginning which was very similar to fallout 3. You started in a vault where people who had been affected by a strange type of radiation and survived live. You find out one day that one of your closest friends has escaped the vault in order to find out what happened to the world, (she receives a radio signal or something that tells her about something.) You then of course follow her in order to find out yourself. It turns out that the radiation started to grow and spread throughout the entire world, killing almost all of its inhabitants or turning them into weird zombie like creatures. I actually hadn't decided what happens at the end, but it was going to be very weird, as all of my rpgs are.
Pics:

This was the common room in the vault, where you could go to hang out and just relax, it didn't really have a purpose other than as color.

This was one of the rooms in the vault, of which there were many, again, except for the players spawn room, these were all meaningless unless you were role-playing.

This is the cafeteria in the vault, kinda generic.

And finally, the classroom, where all the little vault children could get an education.
Complete Crap
These were an rpg that never really got anywhere at all, I didn't call it complete crap because thats what I think the build is, but because it REALLY never got anywhere.

Eriana
This rpg I actually may bring back from the dead with my evil necromantic powers, as I've been inspired shall we say. It was going to be mainly based on going out and completing dungeons with multiple players. I was building the dungeon system to work similarly to the one in mabinogi, if anyone has ever played that game. There was really no story, but it was going to be different than a lot of other blockland rpgs.

This is a shot of the starting village from the bottom part of it, you can see the inn and two generic houses.

This is an overview of the whole village, it has a market, forge, inn and a bunch of generic buildings.

This is a picture of the wilderness outside of the rpg area, it has no purpose right now, but it was going to be a generic hunting ground for wood and bots.

This is an exterior shot of the first dungeon, it has one guard and is a sort of bandit fort in the woods.

This is the first room in the dungeon, anyone who can tell me what this is based off of gets free candy.

And finally, this is the first room in the dungeon, a meeting/guard room for the bandits.
Major edit:Land of the Ancients
I can't believe I completely forgot about one of my rpgs, and the one I think had a moderately good build. This rpg was inspired by titan quest and was set in an ancient world setting, it was going to have multiple areas and places for the player to explore and would have many cities that the player could go to to sell of the fruits of their adventuring. It was never going to have a full storyline and would be very open ended so the players could rp and create their own stories.

This was a general shot of the Greek styled starting town, the interiors of the buildings were never finished so that would be why Im not going to show them.

This is kind of a bad picture of the docks, but I wanted to show that area because I think it came out well.

This is the town square in the Greek town, complete with naked statue ;)

And finally this was an area that had a lot of parts of the Egyptian styled area in it.
Anyway, I hope you have enjoyed this journey through the easily bored mind of me, and as I said before, I may start working on Eriana again.
EDIT: you may rate x/10 if you wish on them all, or on one in particular, I don't care.
