Well, maybe that is their target, action figure collectors who might decide to give their game a try?
To what end? The 4H are not a TTRPG company. They are a toy company. Why do they -want- people who collect their action figures to 'give this game a try?' It's circular logic - the game has to exist so people can try it, and people want to try it because it exists. And the entire history of TTRPGs already has ample evidence that they're unlikely to convert very many people to suddenly becoming gamers. Which means the core audience for a TTRPG needs to be people that already like and actively play TTRPGs. In which case you're back to - TTRPG fans don't care about this project because it's clearly designed for action figure collectors.
I feel like those of you who are very into the TTRPG stuff are assuming this is for you, and not casuals who might be intrigued by connecting the toys to a game in a direct way.
Those of us who are very into the TTRPG stuff have the experience to say what -gets people into TTRPGs-. I've been watching people get into, and get out of, TTRPGs (and wargames) for 35 years. Go back to, for example, how many new TTRPG fans were created by there being an official Star Wars game? In my experience - startlingly few. You know who played it? People very into TTRPGs that were waiting for a good Star Wars game. That's who.
Especially now, in the year of our dear and fluffy lord 2026; there just aren't very many people out there, certainly not the kind that follow Kickstarters and pay 40 dollars for action figures, that don't know what TTRPGs are and haven't had at least some passing familiarity with them. If you're a huge fantasy guy, the kind that really gets into something like Mythic Legions to begin with, you almost certainly know what D&D is and you've already decided whether you want to try it or not.
I'm not disputing that this may have limited to no appeal to folks who buy dozens of games and have the miniatures and all of that. But it may have appeal to others?
The issue is - what others? The people you're talking about are the people that play TTRPGs. It's like making a series of golf shoes with stupid Mythic Legions names on them and saying 'yeah, golfers don't want these but maybe NEW people will spring up all over the place that suddenly really want to play golf because they can finally do it with their favorite Mythic Legions character emblazoned on their feet.' It's just almost certainly never going to happen.
Anyway, they pretty much said that you only break the action figures at specific times for specific purposes, while using the matching miniatures most of the time.
Yeah, I know. That's way dumber. You've just added a very finicky, pointless, stupid gimmick to the part of D&D that's already long and complex. Which, again, any actual D&D player would know -- and they don't, because they're not. They're fucking carpet baggers (and thieves, and liars - I feel compelled to always add).
Also, the figures-in-game idea is cute, but the logistics of stopping play so you can change your maps to put a bigger map on the table and then populating that with giant figures that require posing and remaining steady enough to stand while everyone is rolling dice and checking their books for rules clarifications and everything, that all sounds like a huge pain to implement for real.
True story... I tried to run a little one-shot for my son some years ago using HACKS figures because he loved HACKS figures and was interested in gaming. It was a fucking nightmare. Granted, I knew it would be a bad idea - but I was hoping I could make it work at least well enough for my son to have a good time. It's definitely not the same as trying to please a table of legit TTRPGers. And it still sucked asssssss.
In the end though, it's the thing Shawn Merwin always says about game design: if people are playing the game a year after it comes out it's a good game. If they're playing it five years later it's a very good game. Ten years it's a GREAT game. If nobody plays it, it is what it is.
And I would bet money that no one actually plays this fucking game, basically ever. In fact, just judging by comments here and elsewhere, no one even fucking intends to. All the defenses for this amount to 'but what if someone DOES want to?' It's never '-I- am excited to play this game.' Like ever.
