The costs to make a game of this scope is way above any pokemon spinoff made.

I don't think even that will cover up the expenses.

4 million? New Super Mario Bros. U hasn't even reached 4 million, and it's the best selling Wii U game.

The cost would primarily consist of the creation of new animations. Which price would depend on the target system. Depending on hows its done it doesn't have to be that much more expensive especially if they use an existing engine. A greater problem is that they don't have 3D pokemons on the scope of the gamecube games on the Wii or Wii U.

Nope.A world this big at the desired level of detail will.

"That open world Pokemon game, where you're participating in real time hack and slash, almost Devil May Cry-meets-Legend of Zelda-like combat. Using the Pokemon you caught and trained with the moved you specifically costomized and chose to get the best results in your matches, you adventure through this Pokemon world as you've never seen it before. Climbing mountains. Sailing oceans. Flying unmanned skies. Being hoisted by the strings of an epic campaign with an epic score and epic boss battles until you've finally beaten this epic of a game. Traveling the land, you meet a mixture of both NPC trainers and real ones alike, all in the same world, much like how Destiny does it."

Pokemon had mountains, oceans and skies before. The difference? As you've never seen before = expensive.

The games can improve on a lot! But what you want is not Pokemon. It's a completely different game.

If it was called Mario: Let's go fly with planes, then it wouldn't be a Mario Kart game. What you're proposing is Pokemon: Less Pokemon, which would make it objectively not a Pokemon game. Changing the structure of it's combat doesn't change the core elements of the franchise. You're still a Pokemon trainer with a team of six Pokemon battling for whatever story reason. As long as you have the 18 types, and the complex arangement of attacks, it doesn't matter how those moves are portrayed. That's why Pokken Fighters works as a game. That's why Pokken Fighters is so anticipated. By stark contrast, giving Link a machine gun completely changes the world he's in, the way he interacts with enemies, and the way the lore of the series is percieved to something that is not at all Zelda anymore.

You aren't "catching them all." You're "catching half." That's not what Pokemon is. It would be a critically hated subtraction, and no one who understands the basics of the Pokemon franchise would ever suggest anything like it, because it goes completely against what the franchise is. Pokemon Dark Days can work, but it wouldn't be a game with less Pokemon. It would be a game with dark days. A darker Pokemon game would work. A reductive Pokemon game would not. Less options would not.

It doesn't matter if the Advance Wars games are happy go lucky. That's not what I'm criticizing. Advance Wars is a series where the permanent loss of a character wouldn't change the entire franchise. If one singular Pokemon dies in a Pokemon game, no one would be pissed. If a million Pokemon die in a Pokemon game, no one would be pissed. If 360+ entire species of Pokemon were sudden retconned out of existence for any reason at all, literally every single Pokemon fan would be enraged. I'm trying to be polite, but that is the exact opposite of sense with a game like Pokemon. 

I never said I wanted a Pokemon MMO. Destiny isn't an MMO. Watch Dogs isn't an MMO. Dark Souls isn't an MMO. Journey isn't an MMO. Just because a game allows for moments where the world is shared, doesn't mean that it's suddenly an MMO. I hate MMOs. People who talk about a Pokemon MMO are deluded. The game I described is still a strategic game. Hack and Slash games are strategic. So are fighting games. They are just more involved and frankly more fun than turn based games.

Look, I actually know the costs that go into video game development, not budget which includes stuff like marketting, distribution, and server fees, asset creation is the most expensive of what goes into actually making the game.

Climbing mountains, sailing oceans, flying unmanned skies are all different ways of saying traverssing a map. It incoporates modelling of terrain, textures, creating physics and lighting effects etc. However, that is nothing compared to making hundreds of animations for thousands of models. There is a reason  COD has 100s of modelers at one time on it. Those modellers cost a lot of money.

I never said all regions and I never said MMO. Pokemon is already open world, so I really don't see much to "go into."
