Definitely not what I expected from a "deep simulation" of democracy.
I bought it because I liked the concept that everything influences everything and that you gotta keep balance on everything. This is a huge plus of the game, while I found the rest more or less disappointing.
After some rounds you find yourself just clicking from turn to turn (each turn equals 3 months) to gain more political influence, which you can use to introduce new policies. That is quite monotonous, since nothing really happens except for some decisions you gotta make (i.e. allow fracking yes / no; appoint a more open-minded / conservative judge, etc...).
What disturbs me most is that it does not really reflect the way a democracy works, at least not how I perceive it. In the beginning you can choose the country you want to gouvern, that slightly changes the starting circumstances, but no matter which country I choose, I get the feeling that the system of Democracy 3 is influenced a lot by the American "democracy". There will be only 2 parties and as the "ruler" you have the full power over the political system. You do not have to justify towards your party. I expected that as a leader of a socialist party my party members would punish me for abolishing social welfare, but that does not happen.
Furthermore, since you always need to get the majority of votes, you are obligated to make moderate politics (which makes the extremism extension quite useless imo).
The last thing is that the game is really easy. The first election is always difficult to win, but since most policies have more positive than negative influence and you can introduce more and more of them, from the second election up to the future I won with >95% of the votes (which is completely unrealistic). The economy is not THAT easy to handle, but it is possible and as long as you don't lose yourself in debts, it's okay and not punished very much.
Overall, the game has some nice ideas and features, is overall quite well balanced, but lacks depth and what I thought would be "endless possibilities".
