Well, it's paradox games anyway, they are pretty notorious for releasing buggy games but they usually fix them after all and provide good and long support for the games, it's just takes a while
It's not only HoI games, more or less all their games are like that.
But yar, HoI had some major flaws at first (which kinda made Japan impossible to play since it could not be supplied properly for example...) but most are supposed to be fixed by now.
Performance had some major issues too especially since they put such an advance system for weather simulation it was hogging CPU like crazy (and yes, weather simulation has a point into a wargame, planes couldnt do crap by bad weather in WW2). These are also supposed to be fixed.
I believe the sales is for the upcoming Semper Fi expansion for HoI3 that is coming up in few months, they probably want more people having the game so they are tempted to buy the xpac.
I think I will pass on EU3 though, not enough time for such a time consuming game right now when I got so many other stacked
@kianweic: Majesty 2 is not bad, not a super duper good game but it can keep you entertained for a while.
Do you have In Nomine? I heard it's damn good. Tempted to get the EU3 bundle just because of that.
