i would really like things from fallout 3... like more super mutants.... and more Unmarked areas and more people to fight like the enclave just to be clear i said LIKE.....
and some marked and 1 of them would be like Fort Constantine also have more Unmarked quests that actually give u armor or a special named new gun...
also i do know that who ever is making the dlc are done making them but i thought that it would be nice for some of this to included if they did make another Dlc
