I did not see a suggestions box, so i thought i would make one and leave my own suggestions.
1) Waring tribes :- In the wastes many mutations happened to the poor animals of the old world, which have formed into what some would call monsters, but to others it has given new forms of life, and upgraded the creatures social well being.
Waring tribes follows the story of two such creatures, The Riben , a tribe of mutated rabbits, that over the years has grown in size and smarts, though they speak no language that we can understand, they do communicate in the forms of laughter , growls and a mumbling which their little ears can only under stand.
The rabbits are different colours, mixing from white, to a healthy green glow. They love to tinker with objects, scavengers and traders often put up warning signs, not of evil creatures, but to keep an eye out for thieves, the younger ones will often steal weapons, and gadgets.
The Riben stand around four foot high, and boost an a un natural amount of enemy weapons as their primary weapons, with robot guards. Riben have also been seen blazing across the wastes on high powered bikes that do not even have wheels?
Next is the Tik'on. These are turtles that stand around 5-6 foot high, are incredibly smart, and powerful. They are often found on large oil rigs, or old ships which they convert into moving city's. The Tik'on are every docile animals, they will often never provoke an attack, and if confronted they will often hide in their shell. The Riben hate the Tik'on simpley because of jelously , Tik'on are often well loved by every one, since no matter who you are or what you have done they will trade with you, do business and sort out your accounts at the same time, some see them as boring. They do speak English, though in a very.... slow.... and... dull... voice.
It is up to the player to Stop the Riben attacking the Tik'on, or fuel it on, maybe work it to their own advantage ?
2) armour upgrades and weapon upgrades, in new vegas you could upgrade your weapons, i just want these concepts expanded so i have 100s of options , also to armour, for example leather armour mark 2 can be upgraded with a steel chest plate, making centre mass hits do less damage.
3) Televisions. So in fall out you have radios , yet their are also tvs about but you can not use them, it would be nice for holo tapes to be hidden across the fall out online world, that will play the comical cartoons such is in the intros to fall out 1 and 2, the vault tec adverts, warnings about what to do in the event of invasion , random stuff, funny things
Thats all i got for now... but i shall be back!
