If they really do mean no level cap, I hope it means they are going to have the Fallout and Fallout 2 system.
There will have to be a cap with the new game. Or else every character will become a god and the enemies will become insain bullet sponges. I know some people in the new generation of fans like that
Even if they are talking about not having a end to Fallout 4. It does not mean New Vegas will get a Broken Steel DLC. Which the Devs have already said it will not.
The Endings have got a better responce from the new generation. When people found out there was going to be an ending, the forum exploded with rants against it. But now many on here are ok with the endings or better like the endings. Alot of people on here are new generation but went and played the original Fallouts and have come to love them.
If you are a new generation fallout "fan" and have not played the Originals. Play them. Only cost you something like $20 for Fallout, Fallout 2 and Tactics and a pack and one weekend (depends on how good you are at playing RPGs)
