I support this suggestion.  Easier than having to drop back to the menu and load a quicksave.

And if there are people that like a more "hardcore" experience, then there can be a pre-game option to disable the "redo" button.

Wat? Seriously? This would totally break immersion for me. Please don't do this.

I would prefer not to have this option. It would break immersion and take all the risk out of tactical decisions.

It's not "Hardcore", it's "default" experience. You ask for a "softcore" experience. "Hardcore" would fall in "No saves except for autosave when about to leave the game". 

I'd vote no for that option but if it were to be in I'd just ignore it.

Oh but it does. People expect the default options to be the legitimate way to play the game. Putting this option in by default would tell people that there's nothing wrong with doing a battle over again if you lose. Also more people would moan and complain about how easy the AI is. I trust to the developers to never implement something like this. Save scumming is a bad practice and will ruin the game experience, there's no reason to encourage it.

"Save scamming is bad practice" is an opinion, not a fact. I don't see any good reason to insist that everyone play the game the way you do, Sarudak.  I'd be OK with having the "default" UI lacked the redo button, so that "out of the box" the game behaves the way "most" people want, but I'd like an easy way to turn it on.

I guess I don't understand why there is such resistance to this idea. It's not something I would use (in fact, I'd love to see the opposite, a complete "hardcore" version that didn't allow for any reloading), but some people might enjoy the game more if the ability to instantly replay a bad battle was available to them.

I mean, if this is included on the easiest level, or is a settable option, I don't see where the harm is. Sure, I would vote that it isn't on by default or part of "normal" or whatever, but honestly some people might be looking for a more casual experience.

Some people do use cheat codes and still enjoy the experience. I don't claim to understand it, but it's true.

It's already in the game, it's called 'save' and 'load'. If it could be implemented so that it's faster than reloading the game, it would be a boon for anyone who wants to replay a fight differently, and not harm anyone else.

Put a different coat of paint on a concept and people freak out apparently

Well as save/load is already in the game why waste precious dev time on such a "feature"?

I absolutely agree with your idea to also have a complete "hardcore" version with no reloading.

I love being able to play a game in all different sorts of ways.  When I'm a newb, or when I want to experiment with different ideas, a redo button would be great.  When I want a real challenge, then hardcore "no save" mode would be awesome as well.

I find it hilarious that some people are getting upset because some guy in another state may be playing the game differently than them .

There is no right way to play the game.

I have a counter-proposal. Allow saving only when quitting the game, or save regularly, but reload loads only the last state. Whatever happens, happens, deal with it, or restart the game. This constant reloading kills gaming. 

To OP - try and force yourself not to reload. You will become a better player, and you will find out the games are more enjoyable too.

Now that is hard core

For me personally i would like to see a replay button but only if you allowed the CPU to fight the battle for you, that way you can replay it if you don't like the outcome. Once you are in a tactical battle though you should not be allowed to replay the battle again and the results of that battle become final.
