This is a pretty broad post and I’m really just floating ideas because Devs for need to European Reworking.
We have seen various new flavour features introduced - jingles played when certain cards are sent, increased diversity for European explorers and Battleships, minor unique features for otherwise shared cards, culinary references, an expanded mercenary roster (and greater access through politicians, Church cards, and shipments in general).
I think minor changes of this sort are a good way to add more personality to existing (and new) civs with minimal impact on balance and minimal requirement for new work on assets.
Not every civ needs a unique version of every feature, of course, but I think more cultural and historical references makes the game more engaging and fun.
Prime candidates, I think, are:
— Forts
Sweden’s ‘Kalmar Castle’ experience aura, Russia’s Rekrut construction feature from ‘Pjotr’s Toy Soldiers’ (especially combined with ‘Sevastpol’ - I think they should move the construction feature to that card), the various boosts that Malta gets are all examples of variation for European civs (and then there are the features for US and Mexico, and revolutions).
I think modifications to attack (fire? organ gun? multipliers against certain unit types?), or economic benefits (minor resource trickle when units present nearby? some kind of boost if close to trading post or native site?) could be interesting to play with.
— Factories
Mexico (and the California Revolution) get a special improvement. I don’t see why European civs shouldn’t also get something. Maybe a bonus for one specific resource setting, a small ranged attack, the ability for Explorers to rebuild lost Factories, or a change to the unit production (to produce other artillery?) could be interesting.
— the Theatres card
The Germans already get ‘Witch Hammer’, but every other European has generic ‘Theatres’ which grant Ronin (especially boring for Portuguese given they get Ronin from cards and the politician too).
Every European civ should get a different mercenary or (improved) outlaw unlocked - preferably one that they don’t already gain the ability to train (through their unique church card or the mercenary contractor politician, or otherwise).
I think references to performing arts, folkloric outlaws or culture-specific leisure establishments would be the most obvious - there could even be snippets of relevant music if appropriate.
The Dutch ‘Buckriders’ could be rolled into one card with this, for a start. I’d also like to see a Portuguese version that gives them trainable Cannoneers.
The British could get a reference to Shakespeare (Much Ado - Elmetto; Antony and Cleopatra - Mameluke; Hamlet - some Danish unit which might be on the horizon; there are plenty of options) - or they might get reliable/improved Pirates and have the card play a sea shanty.
The Russians could have ‘Mariinsky Ballet’ and Italians ‘La Fenice’; play some Mussorgsky for the former and Verdi for the latter. Maybe the Russians can get reliable access to Cossack Daredevils and Italians to an outlaw version of the Plague Doctor treasure guardian (though I grant there’s no particular tie between those and the card names).
I’d also really like to see reliable access to outlaw versions of the Colonial Gunslinger/Looter/Officer/Swashbuckler/Oppressor guardians (though maybe that would be more fun for the South African revolution or a full-fledged Belgian revolution - which we might get if there’s ever a second African expansion).
— Advanced Building cards, various unique economic cards, TEAM cards
We have Trading Posts, for example, that get special relevant cards like ‘Greenwich Time’, ‘House of Braganza’, ‘House of Osman’, as well as ‘Silk Road’ and ‘Merchant Republics’. I think some of these cards should be combined with ‘Advanced Trading Posts’ (maybe with its usual effects moderated somewhat). Italians also get a special version of 'Advanced ######## ## ######### ######### ##### get ‘House of Nassau’ (which should absorb/replace ‘Advanced Market’), and there are various others that provide discounts on tech, unit or building costs (‘Louvre’, ‘Mosk Construction’, ‘Reichsritter’, ‘Spanish Road’, ‘Cold Water Port’, ‘Great Lakes’, ‘Patriarchy’, etc.). Then there’s also cards like ‘Coastal Defences’ which should just be part of ‘Advanced Dock’
I think often the shared ‘Advanced [Building]’ cards, civ-specific discount-providing TEAM cards and less common unique bonuses go underused. So why not roll some of them together to make them more powerful and more appealing?
Similar to the above - there are a few civs that get special versions of shared cards, or unique economic cards. The French get two special trickles, the Maltese get ‘Sicilian Supply’, There are also special resource cards like ‘Guardia di Finanza’ and ‘Trip to Jerusalem’. I think more economic cards that are stronger for specific civs or provide some extra, unique, but not too powerful bonus would help to differentiate play styles and improve the experience/texture of play.
— Infantry/Cavalry/Engineering/Navigation School
On the above point - the French, Turks and Russians currently get variations on these cards giving them some bonus units, an incentive to use their own roster, or a bigger bonus for infantry. I think more variations on this would be good.
— the Grenade Launchers card
‘British Grenadiers’ and French Young/Middle/Old Guard techs provide something like this; I think I have previously suggested the Spanish version could be used to separate access to the Soldado/Hacienda. I think any card that modifies features of a unit, rather than just its stats, deserves some differentiation between civs.
— the Town Militia card
Turks get a special version, and with it being included in so many revolutionary decks, it seems like it could be fleshed out somewhat. I’d like to see Boer Kommandos for South Africa and this could be a way to do it (what if it temporarily converted all your Settlers into Militiamen for 15s?).
— the Pioneers card
Similar points as for Town Militia. I think Italy, as well as Japan and the Incans, get a special version of this, but it would be nice to see more diversity for Europeans.
—- the Revolution card
I believe that more new revolutionary countries in European civilization will have more unique cards and units to resist the uprising of monarchy and authoritarianism,I am glad to see the diversity of the unique revolutions of European civilization
