I am reviewing Victoria II, and I have written some stuff about my impressions so far on the message boards over at Blue's News (in a news topic about Patrician IV, of all things). Enjoy, or not (I am JaguarUSF, aka James Allen, of Out of Eight fame/infamy).
Here is your problem, you say this "POLITICS: nope, no reforms to do. Political party seems OK to me." and then say this "PRODUCTION: nope, all of the factories are started automatically by capitalists". if you want to build your own factories then your ruling party is most definately OK. Get rid of those weak willed Conservatives of Metternich's Faction and get the reactionary Neo-absolutists in. Then start building your factories.
