OK, so Fallout: New Vegas is coming out soon ( Hopefully next Q ) so I thought I'd talk about my expectations and wants for the game.  
 
First, let me start off by saying I am a Huge fan of Fallout 3. I beat the game and completed most of the DLC excluding Mothership Zeta and Point Lookout. Everything about the game was so very close to perfect, but unfortunately it does face some minor hinderances. Luckily, a new Fallout game has emerged, Fallout: New Vegas. It has new developers ( or rather old ones because they are the devs from the former, original Fallout), but it still keeps our beloved Bethesda engine. This means that the new game will include the same style of gameplay but optimized to be even greater. Let me elaborate: 
 
Why Fallout: New Vegas Will Be Great: 
 
1. The Fallout universe is one of the most incredible and imersive places you will ever visit in a video game, and better yet it takes place in a setting most of us are familiar with, Vegas. Also it is not an exact replica of Vegas at all. Instead, it is Obsidian's take on post-apocalyptic Vegas. 
2. Enhanced combat including better melee and shooting mechanics. Hopefully, this is a sign tellling us that the new Fallout will be more of a shooter, and less of an RPG in regards to the bullets having a mind of their own. 
3. You can choose from multiple character backgrounds adding an experience close to that of Dragon Age: Origins. And you can be a GHOUL!!!  [ RUMOR ]
4. Hardcore mode where you actually have to try and survive by using items. [ RUMOR ]
 
Hopes and Dreams: 
  
1. More weapons. Not necesarily more different weapons, but more types of weapons for certain certain groups of guns. Also attachments would be great. 
2. A robo-horse as advertised in the loading screens of Fallout 3. Some of the DLC was in the loading slides for the game and they showed a robotic horse in one of them. 
3. Open world for realsies and not by having me pay for DLC, even though I will buy any DLC they make. :) 
4. More noticable karma system. I got attacked by the Talon company once in Fallout 3. Never again. And sometimes a woman gave me shit. I WANT MORE DAMMIT. 
5. More houses to buy like in Elder Scrolls, and more crap to put around my house. 
6. I need my VATS.  
7. Don't change the Bethesda style too much, but please make it better with less glitches and stuff. 
 
Thanks.
