> And you have to buy each figurine and paint it yourself...
This is a _feature_ for the target audience. There's a sizable chunk of the playerbase who enjoy painting more than the game. I even have friends who paint these miniatures professionally as their side gig.
> And people are spending all their money on this?
No. Most people are playing at home on a budget, similar to other board games. A very tiny fraction of the playerbase plays competitively and have larger collections.
> I feel like people could just use AR glasses for this and spend nothing but their time.
You can play this game in Tabletop Simulator, which supports VR. It's _far_ less fun than playing in person with real objects. TTS is mostly used to test strategies before committing to buying the required miniatures.
As sibling comment mentions, the damage calculation is rather simplistic, and it's an exciting moment around the table when you roll a fistful of dice, kind of like gambling. I'm not even that proficient of a player and I can calculate a 17 dice roll attack while sleep deprived at 3AM, no computer needed.
