Before I begin, let me start off by saying that this will unlock a lot of KeeperFX potential, and imo, this feature is really needed.
What would it be? Simple. A KFX release/mode that will never be updated, never be changed. It doesn't have to 100% mimic the OG DK, as long as it stays constant, it's fine.
Updates are great, sure, and it keeps the devs busy, but they're not good when it comes to competitive play (speed running mostly, you want to keep the versions between the players 100% identical).
This is for obvious reasons, like I could do a full game any% run today, and then tomorrow some update comes along, such as selling/building entire rooms with 1 click, queueing up long lines of rock digging for imps with 1 click, or what have you, to basically make beating my run much easier for whoever tries it in the future.
This is actually the one thing that's been keeping me away from doing a full game any% WITHOUT transfer creature run (which has never been done before, by the way, and therefore could be very interesting).
Now, before anyone mentions this, there is a big difference in officially implementing this feature via a command line parameter, or some sort of box you can tick in the launcher, or even an entire different KeeperFX release (called KeeperFX Comp or something), vs downloading some sketchy .cfg files from god knows where. Even editing existing .cfg files is too 'informal'. Only discord regulars would even consider downloading stuff like this, the general population would never go for it.
This is why it has to be implemented IN the game somehow, or like I said, as an entirely different KFX release.
Another project which I've been meaning to do, but am hesitant with, is creating my own campaign, which will have some extreme levels. A slight variation in an update could potentially break my level, making it impossible to beat (like removing wall clipping or diagonal running or whatever for example). Or it could make that extreme level quite a bit easier, therefore undermining the accomplishment of beating it and my efforts of fine tuning the gameplay to suit a particular version of the game for a particular level of the game.
So this wouldn't just benefit speed running.
And one more thing, while we can agree that horny was 'broken in OG', horny might be too op in KFX, at least for the speed run version (if it were to ever be made), as he can slay the samurais in level 15 in just 4-5 seconds without pretty much ever missing, it's barely even a fight. In the OG speed run of level 15, horny missed plenty of his shots on the samurais which kinda added a level of unpredictability/excitement to it.
What are your thoughts?
