Funny you mention grinding is a way to make games longer. You're right. But you can abuse the grinding system to beat the game faster. In Pokemon, if you grind to level 15/20 at the very start of the game. Which X/Y has made that extremely easy now. You can clear the entire game with one Pokemon, in two days.

Kinda slows down the game

Yeah but you'd better REALLY love battling or else you risk getting sick of the game on day one lol. It's happened to me before. 

Never happend to me, personally. I've done it many times. Barvely default was a fun test. I wanted to see how high you needed to be at the start. To be able to handle the whole game. Without getting stuck at grind points. I had to be level 30 to be able to play nonstop. With its fast foward and increase random encounters. I was able to do it within a week.

Turn based and action based RPGs can co-exist. And they will. I don't think action is an evolution for turn based.

The strategic aspects in a well made turn based RPGs come from the ability of micromanaging every command for your party members.
On the other hand, The strategic aspects in a well made action RPG come from being 100% of time in control of your character; timing your defensive or offensive stance, taking advantage of the elements of the environment, and perhaps from the overall control over the AI of your party members if a such a system is included.

Action might be the more preferable one nowadays because it makes you feel and live the heat of battle better.

The majority of people who think that way don't have the patience to even play a game if they have to wait more than 10 seconds until action hits

It also has to do with the game itself. There are a lot of generic turn-based games out there who made it really boring x~x I own a few PSP RPGs which have a "average" turn based system but the way the game and system is presented is so boring I can't play through it.

Some games are better at showing turn based than others, I love how Final Fantasy X and 7 did turn based, the entire Dragon Quest series does it well, Shin Megami Tensei does a great job at turn based as does its various spin offs like Persona, and then the big one being Pokemon. It's not outdated, anyone saying that is full of shit. A core mechanic like that cannot be outdated, the way it is handled and presented can be -but not the mechanic. That's like saying chess is unplayable nowadays since you have to take turns

Turn based IS outdated. It is outdated because ti only existed due to hardware limitations for space so that developers could make the games longer and include more content. It limis the control of the characters and how many characters could be on screen at once. Turn base combat is not a basic gameplay mechanic, it is a combat design.

Street Fighter is a fighting game and has added tons to the combat. 2D is not a mechanic, but a perspective. See Castlevania Sypnhony of the Night as a 2D game that added tons to the combat and character abilities, but stayed 2D. RPGs are no longer 2D so that does not help your argument for why they stick with the outdated turn bases fighting system. You comparing selecting options from a menu to attack to the freedom of jumping and running is laughable.

You can do a lot with run and jumping as most games include those abilities (except turn based RPGs) so they do not liimit the movement and ability of the characters in those games like Mario.

I don't play Pokemon. No specifically for that reason, but that would be one of them. I have chopsen to play something else and so has the rest of the world, which is why JRPGs sell poorly witht he exception of FF. Turn based was the reason why JRPGs became irrelevant last generation. Amongst other things. Something like Disagea fits perfectly with turn based, because it is designed overrall with a grid laytout and you do not have any exploration int he game.

Chess is just that, a board game and all you do is use strategy, which is where the appeal comes from. The appeal of the RPG genre was never in turn based combat. You people who can't let go of the 0s are the only ones who think that waya nd always let nostalgia cloud your judgement. Chess is a singular game as not all board games play that way and video games are ever expanding and evolving.

Great way to generalize. I have probably been playing games before youw ere born and I am far froms tupid. Turn based is boring and takes no skill whatsoever. All you have to do is grind until you level up. Bloodborne takes far more skill than any turn based system and it actually needs strategy and patiens in order to defeat the lowest level of enemies. Notice BB has outsold any JRPG not named FF for the firs time in forever. Continue with your childish elist way of thinking though since you are obviously over compensating for something else.

The thing about Turn based combat is that its redundant when tactics aren't in play. This is a major flaw becasuse the reality of most RPGs is that you spend at least 40% of battles just spaming the same attacks. Theres room for it to grow and be improved upon but devs seem quite lazy in that regard and just jump towards action RPGs as an easy solution. The tactile and reflex elements mean that even when tacticts is removed, the combat is still somewhat engaging

Turn based can be kinda fun, but it's definitely my least favorite battle system, and i find it kind of dull. I tend to tolerate battles in turn based games, whereas with action RPGs i look forward to them.

I love TBS's, though. Somehow when you add a grid things just get so much more exciting.
