totally agree , after so much years , I am still playing and modding HOI2 (Doomsday Armageddon , Vanilla , no mods) and I like it , had the chance to buy HOI3 when it came out , but passed it , because of the initial negative reviews. had the chance again last summer do buy it and passed again. HOI2 is still a great game.
yes , sometimes the IA do what it wants , but still a great game , even without mods or expansions like AOD or the others available for it.
so far I played a lot of games with most of the nations at every scenario since I bought it in 2009 and no game is exactly like the other and that's why I like it and the modding options are simply huge , can't judge HOI 3 and HOI 4 , never played it ,but for what I read in Paradox Forums , some people still plays HOI2 and dislike 3 and 4.
maybe one day they make a Modern Times HOI , then I may drop HOI2 and move there , but until that happened , I will keep playing HOI2 ...
