I would 100% disagree with everything you said as that isn't the game I saw or most people saw really, but I can see we would be on two vastly different ends of the spectrum, so not really worth discussing lol Can't make you like something anymore than I would for another game I don't like.
As for Doom, Doom is fine, it's just a basic shooter. Nothing really new added, nothing really interesting done with the game, it was a pretty bog standard shooter as far as they go today, just all put together in a very slick, modern, package. I think it just comes down to me wanting a little more out of my experience than just mindlessly fighting enemy waves. It's why I don't get into horde modes in games or play stuff like Killing Floor. That stuff has been done to death for years, so Doom rarely excited me. I also wanted to like the music more, but the music only works ingame as outside of the game it's grating garbage lol
*EDIT*
And just to spin this back to actual E3 talk, so that ingame mod system they brought up involved actually buying the mods? Reading on it, mods will still be there, 100% free, but then there will be a separate mod system that's curated, original, third party, content, that you pay money for. It's essentially creating a DLC service within the game. Paid mods didn't work before, I can't see why they think it'll work now.
