I hop around from computer to computer because my current computer sucks. (my good computer was broken beyond repair by a family member.) Now I have to download SK wherever I go. I would like a Portable Application that I can put on a flash drive that I can plug into any computer and run without having to download. When there is a patch, it should update that client once.
That way I won't have to download it everytime I want to play and can even introduce friends to it faster.
I guess you could make a registry file that registers the game and it's key values from the usb.
It's not clean but it'll do in the meantime.
