I have ~140 hours on the first game, but I’m not particularly interested in most of the content shown in this trailer. I find Kojima’s writing to be eye-rolling horrendous and cringe-worthy (I still remember this quote from the first game: “I’m fragile but not that fragile” HUH). That being said, I’m looking forward to this sequel because of the possibility of new gameplay mechanics (like that flood that wrecked the ramp). I'm excited about new weapons, vehicles, enemies and mechs! I wish the trailer has more of that instead.
Not really sure how you can roll your eyes at the dialogue from the trailer, but not from Death Stranding 1 or the Metal Gear games. This isn't any more ridiculous than any other game he's made.
Edit: for the record, I very much enjoy kojima games. I liked MGS games and Death Stranding 1. But there is no denying that his games are all weird as absolute fuck.
