I know what you mean. I don't think I've ever felt as accomplished as I did when I saw the effects of Project Purity.ohgodalex said:It's the feeling that my actions shape the world, that does it for me. After I defeated the Enclave, I really felt like I had saved everyone from a terrible fate, and I was now free to roam the countryside like a god, dispensing my own particular brand of violent and stealthy justice to any who might oppose me.
Seriously, with Broken Steel, Fallout 3 has perhaps the best post-game gameplay of anything I have ever played. It's still so much fun to wander, and there's still so much to do.
