I tested the game this week end, and here are some thoughts.
Please notice I a old timer, both with P'Dox games and programming (33years of experience as programmer, and currently preparing a PhD in IT); that to say if my criticism do not please you, just take a deep breath and move on, they are only (and for what it is worth) just a personal opinion. On the other hand, I believe we would all beneficiate of well behaved discussion (might give idea to the devs).
I played Ger , 33 scenario (patch 1.2).
1) It is still easy to DOW Spain, invade it, annexe and liberate (2 weeks), by so gaining the following advantages : secure foothall to attack Gibraltar, some minor (or even major) tech for free (by so akin as to have +1 tech team in average, and allowing me to tech rush; or research tech that I shall not be able to research!)
2)It is also still very easy to abuse the economical system, 1 jully 1933 and I have reduce my dissent down to 25%, moved the slider down to max planned eco (-2).
3) Lot of money/goods/food can be made just by selling antique techs (1870 infanterie for example).
Notice I do not think I even maxed out those flaws, as I presume I started to sell the tech one month too early (and doing so, not riping all that I should have ripe).
I do admit the game is giving a fresh air to HOI2 (reason why I bought it); but still thsoe flaws (who were described already in vanilla HOI2) are existing, and somehow make the game way to easy. I did not try if the Czechoslovakia trick is still possible (early attack , take the VP without destroying the units, pupet, liberate after the Anschluss); or worst if Blue Emu gambit (ally with Austia, attack as much as posible, let Austria make the annexions and so get the malus for it, then break the alliance and anschluss the whole mittel europa!) is posible.
So ,because criticsm must be balanced with positive idea, I would suggest the devs to improve those points, and the relation that made a small trade (5 food vs 1.2 $ with UK) outweight on the long run the Spanish affair (same here, my relation with UK were almost back to normal).
Anyway, thanks for the fresh air over HOI2; much more interresting than HOI3 in my opinion.
