doesn't make me all that terribly excited. I've never actually finished a game of Dom3 (just got too bogged down by the late game), although I have enjoyed the starts of many games.
Yup. No interface or playability improvements? I could care less about extra spells, there is enough of them. Just fix that damn interface. And make endgame at least remotely playable.
P.S. And it costs more than other recent releases like EU4 or TW:Rome II (at least on Steam in my region)? For an expansion (engine seems to be the same)? Meh.
I do buy more strategy games than i really play for any significant amount of time, just to support the genre, but Illwinter really should think about improving the quality of their releases. As far as things go, i think they're unworthy of my suppport.
Conquest of Elysium 3 was even worse than Dominions 3, game balance was completely out of whack, one of the worst of what i saw in last 10 years in strategy games.
And now they ignore the most blatant flaws of Dominions 3 and re-release it as Dominions 4?
