I mean, the much more obvious answer is that a terminal patient was incredibly thankful to get a sneak peak at a game he may not live to see released, of his favourite series, and was playing the game with my exactly the most unbiased lens.
Which is okay. You don't have to dig any deeper than that, you can just be happy that this person got to play the game.
If it's a real story then of course I'm happy for him. I just don't believe anything on social media or anything that a corporation says. I mean, why would I? We are constantly lied to.
Could also just be a well intentioned skew. A terminally ill person who's already a fan and is getting a special gift from the developer isn't about to say "the gameplay is fine, but it failed to make the most of its niche and has several glaring bugs", are they?
I'm glad people still enjoy this series but I dropped it at Tiny Tina's. Nothing felt new even if it was technically a new class or enemies or what have you. I can't help but feel the vault hunting aspect was dropped too soon after 2.
