Fantasy flight has released a new game and labeled it a Descent game.
They made a very expensive game, with horrible art. The hero selection has no male human/ dwarf fighter characters, no white human male characters at all. The only character that is manly is a black wizard dude that I admit is kind of cool. The male elf ranger character is the most pathetic looking character that they could have designed.
In previous games Fantasy Flight made it a thing to have both male and female represented in their games. The Descent Second Edition game had 1 male and 1 female of every class. You had male fighters and female fighters, male mages and female mages etc. Now in a game that is a freaking 175$ they decided to not include the most popular characters, male human fighters and male dwarf fighters. Their Descent player base is as you expect white and male but they decided to not include it at all in their game.
Sorry for the rant.
Had to make a small edit: One of the characters Vaerix, the Dragon-Hybrid Outcast has neutral pronouns. Cause of course they does.
Specific game system aside, a DM has the responsibility of keeping everyone engaged and having fun, yes. Don't misunderstand "fun", though. Fun is different for everyone. If fun for you is high tension and high stakes with no guarantees from your allies, you can make that happen with a cooperative DM and player group. Finding such a group is the trick, though, and you'd have to find a system that supports those traits in order to have a better kickstart to your search.
From my point of view, it makes sense that people go to pnp for the casual type of escapist fun. They probably have stressful daily lives with regular misery, so of course their game time is going to be in pursuit of the opposite.
Tell your DM to step his game up, then. If he can't keep you engaged, tell him to let you run a session.
