1) The intro stuff was too short. If you're going to make up a background for the player character, you should force people to feel like they're the person in that background. Otherwise there's a disconnect and people don't feel like the background is their background. Fallout 3 did a lot better on this.

2) I think the graphics are lovely, and I'm playing on medium. Some textures are bizarrely bad though, as if they were transplanted from an early 2000's game. Also, the graphical style can be a bit too cartoony at times. I thought the grim-green and gritty-brown filters in 3 and New Vegas were ridiculous, but this is too much; it looks like Mirror's Edge or something.

3) The UI is not appropriate for a PC game. You should've designed a PC UI mode that could've been selected in the display settings. Basically, everything's too big and more inaccessible than it needs to be. Remember Morrowind's PC UI? You press one button and everything you need is right in front of you: map, stats, spells, inventory, character equipment, character appearance. Am I the only one who thinks making the menus handy is worth a thousand times more than making them fancy? Especially for a game people will spend at least 200 hours on? It gets tedious wrestling with the menus for such a long time.

4) The dialogue system is bad. I don't think BioWare's system is really appropriate for Fallout. And if you're really dead set on using it, you could've at least only applied it to the main quest. That way we could get the story driven system for the story, and the previous system for the rest.

5) The whole, general stats/perks/character system seems shallow. Thankfully it doesn't look beyond repair, and I expect to see some great mods making it more indepth and RPG-y. I really think you should've just kept skills and came up with a way to balance them. Maybe limit the amount of points you can put into a single skill at a time, so people can't blitz the weapon skills.

6) The movement is much more fluid than 3 and New Vegas, which is a very welcome improvement. The janky and jittery feel of 3 and New Vegas were pretty awful.

7) The new looting system is great. Looting used to be a chore. However, it does seem to lack a "take all" button, and the inventory window is too short. If I piled a bunch of stuff into a dresser, and I can only see like four of the items at a time.

8) The new combat mechanics are cool, like being able to melee with your gun with a single button.

9) The new armour system is an improvement over the previous Fallout system.
