Personally, the things that attracted me to all the Lucasarts games wasn't the lack of action or having to think on my feet. It was the wit, the immersion, the attention to detail and beautiful backrounds,the intricate characters, and the little touches that made it more than a story, it was an experience. I consider myself a "purist", but I still love intrigue, suspense, and a little danger if they can enhance the overall tale and immerse me a little more.
I feel that these days games that are cranked out with unbeleivable graphics and real life physics have lost that touch, the swagger that really made those early games special. If action can mesh with the rest of the game without seeming forced, I am all for it.
