New feature? An improved core game
My diagnosis is that what is really needed for HOI3 imho is a rework of the core game - and do not make mistake, the "core of the core" game are the 3 land, air and sea combat subsystems. All the other features - technology, diplomacy,intelligence, economy - are important but secondary (What I mean is that, at the limit, they can be automated and nothing essential will be lost. On the contrary, the armed forces system is essential : in HOI3 85% of the fun is in designing, deploying the armed forces and using them against the other side armed forces).
In its current state, this core game is, let's face it, not half satisfying as it should be. It does not need chrome or refinements over secondary features. It needs a good rework of the main system : the armed forces.
The continuous publishing of new versions of HOI2 (DH and so on) is for me a significant indication that
1/ HOI3 is a design half-success.
2/ there is a tremendous need for a good ww2 strategic game.
For two years now, I have come to this forum in the hope of seeing some improvements to HOI3. Purchased the extension, downloaded every dlc, installed every patch, tried every mod. Nothing decisive.
HOI3 could have been a great game if the designers did not try to reinvent HOI2. Basically HOI2 was right for game scale (basic unit division) and tempo. It needed a rework of naval and air subsystem, the introduction of a coherent military hierarchy, a more efficient AI and a few more provinces on the map - and of course the cosmetic facelift allowed by 4 years of graphic exigence.
What was produced was an insanely complicated game (basic unit regiment) with too many provinces.The result is a game that generates more frustration than fun.
My recommendation is to switch to designing HOI4 on the sound foundations of HOI1 and HOI2. The sooner the better. If PI doesn't do it, other companies will.
