Honestly if they re-work France I hope they make it so they're not this weird stereotype civ of "oh hon hon hon we sit back and build les wondres" and even then they're not that great building wonders or benefiting from them since wonder tourism is so bleh. The Garde Imperiale is so forgetable that in one round of musketmen buffs the devs themselves forgot about it.
Spain (is it me or does every historical game struggle to balance Spain? Civ 5, Civ 6, Age of Empires 3....) could have its CUA and LUA tweaked a bit, I think the conquistador is fine, maybe they can make them less tedious by allowing you to link religious units to them like way back in the days of initial release. The mission has undergone several tweaks here and there and it still feels weird, maybe because it's unlocked late in the civics tree but provides science and faith? I mainly play as Spain bc their playstyle - mid-game domination - is like the only kind of domination I do and they're fun when all things line up but it takes a LOT of work to line those things up, and when they don't you're stuck with a pretty blank civ who is supposed to go out and colonize overseas but doesn't really have any innate desire or benefit except some negligible trade route buffs. Maybe not making them so dependent on religion and putting more emphasis on overseas/inter-continental conquest would be better but idk Spain's identity in Civ has always been religious zealot.
Definitely want to see a re-work of all the infamous Rise and Fall casus belli leader abilities like Robert the Bruce's.
Change Spain to an exploration Civ. | CivFanatics Forums
Some time ago, I did a thread aiming to give some ideas that could fit a rework of Spain. It was made in the case Portugal is not present (nowadays, I think it is more probable that they will appear). Maybe something there could be of use.
They are different bonuses that more people participate doing, and I really think some of them are quite interesting!
Maybe taking one of them could work.
The worst part of Spain, for me, is that they are perfect as they are. I mean, the bonuses are superbly choose as they fit perfectly what Spain was during this period under Phillip II.
The problem is that all their bonuses are in different branches so they fail at everything:
I personally love it this way; it is a challenging civ that need planning (and luck).
The bonuses should repay the effort. I mean, as Spain you have not real bonuses helping you gaining an intercontinental empire or to access fast you bonuses.
Therefore, if you manage to activate your bonuses and/or reach another continent, should repay the effort.
Maybe a little bit like IRL, Spain invested much more than other civs to colonize the new continents. At the start was not very lucrative, the gains came more than 50 years after (and after having make many investments) but as soon as they came… OH BOY!
Maybe the same could apply here, you still not get bonuses for exploration, for making new cities or districts in new continents...but if you do, you will receive a massive bonus!
My favorite would be improving the trade lines; they could give incredible yields and have twice the length. This will made other civs try to sack them (and they could give extra gold for enemy privateers) and Spain’s best interest to defend them. The task would be hard, as they would be very extend lines. If you cripple the trade routes, you cripple Spain Civ, just like in IRL!
