This has the appearance of a nostalgic D&D tabletop setting, but is more like a poorly-translated turn-based JRPG, where tactical positioning and well-timed skill choices are not the focus. Instead, players find themselves killing hordes upon hordes of monsters to make numbers go up so they can kill bigger hordes of scarier monsters. The story tries to be humorous about a D&D group finding the line between fantasy and reality blurred with numerous shoe-horned cameos, but the writing itself is unnatural to the point that it feels like a high-schooler's fan-fiction.
Even if you're in the market for a mindless grind-a-thon, don't buy this on the PC. Opt for the mobile version instead, since the game also constantly puts you through miniscule but unskippable animations that would be more bearable if you could look out the window while they play. Hell, I'd recommend other mobile games entirely, but some people like their skinner boxes and this is one of the skinneriest boxes I've ever seen.
P.S.: This game has micro-transactions. Since this game is a grind anyway, you should never need them. Of course, having micro-transactions at all implies that this game is quite purposely putting you through a grind.
