lol it's amazing how many people have the exact same reactions to everything but think they can't possibly be the ones engaged in groupthink.
The trailer seems obviously inspired by the Dungeons and Dragons movie's marketing material, and by that I mean directly ripped off. Taken in that light, it's a fine trailer. If that's the vibe they want to go for, I can't blame them since that movie was popular among its target audience and continues to gain praise as a good movie even if it didn't quite hit the financials the creators wanted.
This is targeting the people who like Critical Role, etc. Those are the core TTRPG "fans" right now, not nearly 50-year-old dudes.
EA's marketing for this series has never matched up with the game you actually get anyway, so it doesn't matter.
