How about a mod that turns the super mutants back into something they where meant to be: Superior humans! The game gimped them, and gimped them bad, simply because you where exposed to them WAY to early. In other fallout games they where one of the least end creatures for a reason, the bloody things where walking tanks! When I first came across them in 3 I gave them a wider birth till I realised I could take them out with a half a 9mm pistol mag and still have rounds left over.
That game did so many things so wrong. Worse is I was willing to give it a wide range of 'changes' cause it was a fresh engine from the old top down style of game play. Advances in technology and all that... but no, it took liberties where it never should have and left all the major changes it could of so easily implemented unimplemented.
Mods I would like to see:
Modified weapons: The addition of home made weapons wasn't too bad but they where all 'exotic' which meant long time to get most of the fancy ones and then you couldn't get more then a handful of ammo for it all at that point. Where was the home made pistols, the home made pipe rifles, the home made blasters. Not to mention the ability to graph scopes and other weapon systems to your guns but also to create a small range of other usable devices that you would see common place in the hands of a good smith and what not.
Fix the stim packs:
I never liked they turned the doctor kits into the stim packs, not one little bit. Injecting yourself with regenerative nanobots, or whatever was in them, shouldn't magically get better just cause you know your way around the human body. Super and Ultra should of been included, with all nasty side effects, cause it doesn't make sense for such a wide spread technology just to vanish now does it? Then they could stop making the damn things so common place, no threat of failure when you are walking around with a million instant 'fix me ups' that could be used in the middle of a battle. I do not jest, the things are so common you have to wonder how people are dying out there.
vehicles:
A dirt bike, that is all they needed to include. So what is some of the player made vehicles, yes we should have to build the damn things, couldn't fit into say the subway. Having safe places to leave them and then going on foot over the more broken terrain or risk losing your vehicle to other scavengers would still leave running people down with your dirt bike quite fun. Mountable weapons would of been nice too, can't tell me with that much fusion based technology there isn't someone out there with a dirt buggy patrolling for the local brotherhood! Savaging cells from cars to use in your vehicular would be a well placed addition to just using those fusion cells as 'det packs.'
Use the whole damn map:
Is it just me or did anyone else see the cut and paste they did on the main story line. How your trudging along and then suddenly, boom your thrown in the last 'scene' with no way out of it and no real warning what so ever that you had progressed that far. If you where not an explorer who went out of the way to do every quest you come across... well, you could easily get there so fast your head would spin. At that point your looking at the map, noticing dozens of places you never once stood foot in and even wider areas of terrain that have... nothing... nothing what so ever... in them? The game felt so unfinished because of this, as if they where being once more pushed to release the game that they had to drop half the potential story just to get the game out the door.
More party members:
Charisma in the first two games effected so much more, but one of the largest things it allowed was more NPC's to back you up. I know why they didn't include this: The game was too damn easy that you didn't need anyone, let alone a posy, but come on. Having an unusual party that was often held together by your will alone was a great experience when your facing a whole base full of armoured grunts that are not going to wait to come at you two at a time.
Those party members again:
And the damn things should be more customisable with their own character sheets. Oh sure you could give your party member a weapon but it didn't seem right. First off, there is a good chance they would not use it while still complaining your not equipping them and second it was as if they where just bots as no matter the weapon they used them all just the same.... I know, they are bots but they felt like it and that was just down right wrong.
Harold:
For those who know the original games... enough said. For those who do not, Harold has ALWAYS shown his deformed tree sprouting face and dry witty humour in the past. To not have him seemed... wrong.
Fix the ending:
Make every town have one sub mission that will produce an either/or ending credit to show explaining how your actions further changed the course of the lives of that town. Bring back the slide show, it made me feel as if my actions mattered and where not just a foot note in the history books, if even that....
I could go on but it is 1:30 am where I am, I will leave it there. I just have to say: fallout 3... Epic Fail as a fallout game.
