I can proudly say I've been playing Fallout 3 since its release date, and haven't ever stopped.
Since then, I've played both on 360 and PS3, but I play almost exclusively 360 now because the DLCs are a mess on PS3 -- or at least I saw it that way.
Unarmed can be useful, I think, when dealing with tough enemies like Reavers, but I never personally use it. Though, I must say, I really want to start just so I can use this 'Fisto!' weapon. Looks veeery satisfying.
In my opinion, all gun categorys are great. Though, at my character's peak, he tends to stick with Big Guns like Vengeance and Eugene, simply becauase with the right perks, you can have them doing 300+ damage... and they look great with Wintersized T-51b. A3-21's Plasma Rifle is my back up, and it has never failed me.
To be honest, I don't have the patience to decorate my house. Most things just get stuffed in a locker. I'll usually by a theme, get a few house items, put special weapons on display and then be done with it.
For some reason, I found decorating much more fun in Oblivion. :shrug:
