I'm just particularly fond of Assassin's Creed Odyssey due to it being the only open world game that is playable as a stealth game with stealth game specific mechanics and a world designed for stealth traversal, there has not yet been any other game designed that way that isn't just light stealth elements that fall apart when you inevitably get caught in two minutes, until someone shows me another game like that, I honestly feel that game to be pushing the stealth genre, which is honestly not hard to do because of the dire state it's in.
And I'm glad you expand on Postal particularly, it goes to show that even games that are despised by many have their own meaningful aspects to be gleaned with the right mindset and with their flaws in mind. I think that when it comes to games of this size it is very hard to be able to say they are crappy, full stop, especially ones like these, or even Deathloop, which I enjoyed. Not as much as Arkane's Prey or Dishonored, of course, but it was still an enjoyable game with an excellent art style and soundtrack that heavily tapped into my love of the 70s, and featured a very nice multiplayer mode that simply doesnt exist in any other game.
