I don't even know what the newest game I even own is... Helldivers 2? Except for Elden Ring and it's DLC, I haven't bought anything close to release for years. HD2 came out last year and I bought it last week.
Baldur's Gate 3 and Elden Ring are the last 2 AAA games I bought close to launch for full price. Other than that, I picked up Hades 2 in early access. The rest of my library is all stuff that I bought on sale.
I do have Monster Hunter and Avowed on my wishlist but I think I'm going to be patient. If I do pull the trigger, it would probably be for Avowed because I want more Obsidian games. On a related note Grounded is $20 on Steam right now so I stopped that up even though I beat it back when I had Game Pass.
Based on the size of the company and the budget for the game I'd at least call it a AA game. My real point is I paid full price for it and have absolutely no regrets.
