Interesting. I actually upgraded my computer solely for the original HOI3 prior to release. And then due to the slowness, upgraded to a high quality video card about ver 1.3 so it would actually play properly. Would not have upgraded it it was not for HOI3...
So spent 15X the cost of HOI3 on a computer just so I could play it... And I don't think I was alone!
Your not. That is the reason I bought a new one.
