I like them both for different reasons as stated above. HOI is simply a War Game, you just want to duke it out and try to recreate World War 2, HOI is your thing. Vicky however is more of an Ecnomical/Country or Empire simulation Game. Yes you can have Wars but it's not when you conquer all you annex (Except for Uncivilized Countries) you basically try to forge an Empire out of Uncivilized Countries and Colonized parts of Africa then when you fight Wars you only gain or lose a few Provinces unlike HOI where you can conquer The World if you desired. Also The Economy is more Advanced, meaning for War Gamers you won't be getting straight away into a fight but having to but have to build up a powerful Economy to begin your Wars unlike HOI where you only need Supplies which can be easily gained. Yes you can lose resources on HOI but not like Vicky, you really have to be good to balance your resources. Still out of playing, I tend to play more HOI since on Vicky, even on countless people's advice, still fail to start a decent Economy (I really am bad when it comes to making Cash) where as on HOI, no problem.
