Yep, best of luck! I played DE:HR when it first came out, and loved the heck out of it. (Also found out the hard way not to take too long in the office before the first mission. Eesh. I never thought they would actually kill the hostages after ten or fifteen minutes. )
If there was ever anything that I didn't like about it, it would have to be that five bars of energy is waaay too few. It's either play the way you want and have to reload far too many times with a long reload time, or get enough energy to do what you need to do without having to reload.
So yep, good luck with the crackin' and whatnot. It is appreciated!
