When the 1.69 upgrade came out, I bought everything on disk that I had originally bought as downloads. That amounted to 7 EP's and 5 SP's, plus a 2009 copy of the base game. Considering how much money I have invested in the game itself, and how much I've spent on successive upgrades to make my computer work well with it, I don't think even a 64 bit version would be enough to entice me to spend even more, to get the same game. I don't have very many problems with the game anymore, and most of them are relatively minor, so for me it's actually good enough.
