I wonder if anyone thought about this. I like the versions of certain softwares or games I can store on my pendrive which I can access whenever I want without prior installation. Some of the older games are easily convertable to portable versions. I remember I was installing Caesar 3 like that on C drive in Sierra folder and then I was copying all installation folder to pendrive and then I was deleting everything from harddrive and then I had working game on pendrive. I was trying to repeat this process with civ 3 but I have errors and nothing its working. Maybe someone knows how to do it.
