Well with Fallout 3 on a few weeks away, i can only say that i'm ecstatic. After the drought of games during the summer, the "games for christmas" are now being released. Great games such as;

Little Big Planet, Saints Row 2, Fable 2, Resistance 2, Gears of War 2, Far Cry 2, Cod:5, etc.

Of them, Fallout 3 will definately be bought before crimbo! My collection is built up of FPS's and i'm after a good RPG. With Final Fantasy an age away and with all these new JRPG's coming out, Fallout has come in at good timing. But with Fable 2 being released not long after, it'll be a tough desicion. Each of it's predicescors have been good games, and each have provided us with hours of gameplay.

Now we know the Fallout series is RPG, but what Bethesda have done with the Fallout series has changed the games origins. It's a lot more FPS & a lot of people have commented it on being a futuristic Morrowind/Oblivion, and to be honest i'd have to agree with them. Nevertheless it has some old and new features in that improve the games longevity:
Customizable Player - True to Elder Scrolls and previous Fallout games
Stats - Able to create your perfect character
Karma - What i believe to be a leap out of Fable (minus the horns), good actions get you respected in towns, and negative actions to things get you in the good books of villians.
Weapons - Toaster Bombs anyone? Well there here!as well as numerous other crazy weapons in the game.
Armour - Same as above, A welders mask, Eyepatch, you name it!
