You know there's something that frustrates me about the people who say RotW falling behind Europe is just some people's fantasies.
1. The game is called Europa Universalis. It's not called Terra Universalis.
2. It's not a fantasy, it's what happened. All the anecdotal evidence of "oh hey these people HERE somewhat held off the Europeans for a time" means very little because it still happens in game. All the time you think you need less troops than you actually do a little conquest war against some American tribe ends up being an annoying affair. They even have fantasty things like Native Americans not just being able to usurp European weapons but being able to get their administrative and diplomatic technology as well. In addition RotW is outperforming their historical selves already so there's already favoritism being shown to them.
3. It's a very small development studio and I'd rather what little time to work they have be done on what the majority of the people buy the game to play. Sure, the Manchu were more important and need some work but there's a hundred reasons why Europe ended up the way they did. Maybe tech costs aren't the best way to show that but it's a lot simpler than a hundred scripted events.
1) It's called Europa Universalis because it's a brand name, and ever since EU2 the game has been expanding in scope of available nations to play. If only Europe should be played, then the rest of the world shouldn't even have been added back in EU3 or whenever they were added. As is, though, the game is clearly not just "Europe-only", and hasn't been "Europe-only" for at least an entire game iteration. Really wish people would stop acting like the name being Europa Universalis means that only Europe should be playable.
2) It's what happened due to things that happened in history. If things transpired differently, then who's to say certain areas of the world would not be as backwards as Europe was at the end of the time period? Who's to say that Europe had to come out on top, if hypothetically Ming became an amazing powerhouse with great administration? If India wasn't in political turmoil when Europe arrived? If disease didn't destroy most of the New World population?
As is, the tech speed ingame is designed to replicate history without the game replicating history and replicating the causes that led to the effects. Westernization is a bandaid to this, because currently tech speeds are hard-coded regardless of whether nations outperform their historical counterparts or not.
3) Europe is fine. The only problem Europe has is that playing the game becomes an absolute bore after 1600 because
they have no difficulty. This is more because Europe is too priviledged and doesn't have to work to attain their geopolitical dominant status that Europe achieved at the end of the era. This is both due to internal problems (or the lack thereof) and the fact that Europe gets to ahistorically walk over nations well before their end date (Muscovy does this to hordes quite often if it actually feels compelled to attack them).
Besides, a large reason of why a majority of player starts picked being in Europe (and European great powers at that) is because they're the ones with the most fleshed out areas. I'm not saying that Aachen needs to have as much detail as Great Britain does, but Europe as a whole has a lot more flavor than playing a Native American. This is getting better over time, but we're still not quite there yet.
