Please don't recommend a requiem for the capital wasteland, that mod is so friggin buggy and so intrusive on your files. It's like the creator was too lazy to create an installer for it.
I'm thinking if there is a mod that will help me craft weapon repair kits, adds new weapons, adds turbo (if possible), more or better armor / clothing, etc., hardcoe mode. Anything that will help me play fallout 3 in a whole new way.
