I don't really have any recent ones, but I think my most recent one would be Doom Eternal. That's not saying that it's a bad game, I can understand why people like it. I'm just not a fan of how it plays compared to the original Dooms or even Doom 2016. My biggest complaint is really about how little ammo you can carry for each weapon. I don't like being forced to switch weapons all the time or else glory kill every other enemy. I wasn't a fan of glory kills in Doom 2016 because I felt like they interrupted the pacing in an otherwise fast-paced game, but I put up with them because you could ignore them if you wanted to. You can't really ignore them (or the chainsaw kills) in Doom Eternal though, otherwise you'll find yourself regularly running low on ammo. I guess at least the chainsaw has more utility in Doom Eternal than it did in the original games (on harder difficulties it's hard to justify the chainsaw on anything except low-tier enemies), but I never finished the game because of the ammo restrictions.
Another game I have regrets about is The Sims 4. I knew I was getting into a dlc-pit but it didn't bother me too much because I tend to subscribe to the "Paradox Method" - buy what you like, pirate the rest - when it comes to games with lots of DLC. Additionally, when I pick up a game and really enjoy it, I don't have problems dropping money on dlc because I tend to play it for hundreds or even thousands of hours. However what I wasn't expecting was that I'd end up pirating the entire game anyway because updates almost always break mods and there's no way to disable updates (Origin let you do it, but neither steam nor the new EA games app lets you disable updates). So what was the point of buying anything if I was going to have to pirate the game to stop updates from randomly breaking shit?
Edit: some games I don't have buyer's remorse for are Cruelty Squad, Bomb Rush Cyberfunk, and Factorio. Those could easily be 2x the price and still be worth it imo.
For me it was how seriously Eternal took itself. Doom 2016 had a story but Doom guy didn't care and was just there to kill demons. It was a running joke how little he gave a shit. Then suddenly in Eternal he can talk, was some kind of Chosen one and there's this grandiose story with Heaven etc and it's all way too up itself. I just want to shoot Demons. That's it. Don't try and make it more than it needs to be.
In Doom 2016, the protagonist gave me those "been there, done that, saw it all before" vibes towards humanity's attempt to use hell energy. He swats anyone away who advises him to wait, be moderate or let them try something else first and simply does his thing. I just don't get what's up with the protagonist in Doom Eternal. It feels like some design-by-committee fake badass who does inconsistent things, he suddenly got that "Fort Grayskull" (or is it the "Power Rangers Fortress"?) place and does whatever the Vega AI says. It feels so whack.
Only time Doomguy talks in Eternal is during a flashback, and one word at the end of the second DLC. During the flashback he only says how he must kill more demons.
Funnily enough, I felt the opposite. 2016 seemed more grounded and serious to me while still having some laughs and eye rolls, while Eternal had a lot more arcadey stuff where it felt like the devs either didn't know how to integrate it more seamlessly into the universe or were just doing whatever they thought would be cool rather than what would serve a good story. I think I would have been alright with either version of Doom, but I feel like there is a disconnect between the two newest entries that is just a bit harder to look over.
My biggest complaint is really about how little ammo you can carry for each weapon. I don't like being forced to switch weapons all the time or else glory kill every other enemy.
I do like what they were going for but I totally agree, I don't want to constantly feel like I'm suffocating (low/out of ammo) when I'm trying to tear through nightmare-level hoards of enemies. Just let me rip and tear!!
I'm a hardcore Quake and Half-Life player so constantly switching weapons and using my full arsenal at once comes naturally to me, but I was still struggling the whole way through the game.
