Grew up on 90s MTBs in the 00s, fell for the fixie meme around high school and college '10s, and now that I have $$$ I really don't care for peak performance Road nor MTB. I just want to cruise around the same dirt roads and trails around me in no rush. I had a gravel bike, it was okay. I saw what you guys meant by being under biked.

Money sorta isn't an issue and for the first time ever I can afford high end shit, but instead of listing after the latest full suspension trail bike or high end proper gravel bike, I just want some old school and as simple as possible.... but capable of mild trails and dirt roads.
I had some trek with 35mm tires. A Giant Fathom 29er.... KHS Zaca... Cannondale F400 I just get bored and want something different, not necessarily/better/

None of my friends care to ride. I don't like group rides. I Don't like riding on the street.

What should I get?

It has to be all black and I'll put on a Brooks saddle.
