It depends - if I have bought it then probably 30mins to an hour. If it's on ps+ I give it about 10mins then I quit and delete. I have tonnes to play and hardly anytime so games don't have much if a chance to grab me.

Depends on the game. I give a lot more time to franchises I love than those I've never played before. If it's a game I'm unsure about and was cheap, then maybe not even an hour. A bit longer if I actually paid for it. While franchises I really love I'm willing to give 20+ hours. Happened recently with Persona 5. Was disappointed with it thinking it's easily the worst Persona game I've played until I got to the summer part. That really changed my opinion on the game pretty quickly. Still, a lot of games I would've dropped long before then, but because I know and love the franchise I kept going.

Depends on the game.

Although its rare for me to drop a game even if its a game I dont enjoy as much as others.

I like finishing games and scoring them.

The only example of a game I dropped was the original Tomb Raider on PC.

I'm not sure, because I rarely drop a game intentionally because I'm not engaged enough. Usually when I 'drop' a game, it just happens. Maybe I've been playing it less and less with no intentional decision to play it less, or maybe I just drop something really quickly because I just don't feel like getting back to it some day, or the next after etc.

The only game I can remember dropping intentionally because I didn't enjoy it enough is the first Halo. I've started it two or three times, and I just can't get further than like level 3-5. I don't think that's very far, so if I find a game boring enough, I guess a few hours is already too much, at least if I think it's not going to get much better. I guess it helps if there's something really engaging even if a game is boring, or if I have reason to believe it's going to get better, which is often the case.

For years if possible. At least be games you wanna revisit down the road.

Trophies have never personally motivated me to play a game I wasn't really liking. But they will make me play a game I like longer than I otherwise would. It's hard to me to stay motivated without a goal, so even getting pointless gold stars can help keep me engaged. Spider-man 1 was actually one of the few games I got all the trophies for. 

I generally am that way, but I sometimes like to try things that I'm not sure I would like. Particularly on Gamepass or if I could get it at a discount. There are some games like Hades, Undertale, Shin Megami Tensei, or Fire Emblem where I didn't think I'd like it and ended up loving. One of my favorite games ever is Kid Icarus: Uprising. I was on the fence about getting it, but I was swayed because I wanted to get the 3D version of Kid Icarus NES that came with it. So, I think it's good to sometimes try a game even if you're not 100% sure on it. 

Yeah. When I was a kid and had more time than money I'd rarely drop a game. Now that it's the inverse, I'm quicker to quit. Although, usually willing to put in more than 10 minutes. 

I'm actually just starting Luigi's Mansion. I loved the first two, but this one isn't really grabbing me. It's been getting slightly better. I can't quite put my finger on it.

In the first game there was a sense of everything being connected in a Metroidvania type of way that made it fun. The second one was level based, but within each building, there was a mini version of that interconnectivity. 

So far in three, it has felt like a series of isolated challenges. Even though we're in one big mansion again (a complaint a lot of people had from Dark Moon), each floor feels very isolated. Not much exploration so far. And, the changes to the catching mechanics haven't made things better so far. I'm hoping the game is just kind of still in tutorial mode and will get more complex, but it's just not working for me right now.

But, as many have said, previous experience with a dev or franchise matter. Since I liked the first two games so much, it's hard to imagine I'm going to drop this one. but we'll see. 

Normally I try to give it til im a decent percentage into the game and realize its just not for me. Unfortunately happened to me halfway through the Dead Space remake so I finally gave up

it's a case by case basis for me. Like if it's an rpg we're talking about. I'll give it about 8 hours before I start coming to a verdict. If we're talking about an action game, I'll give it 2 hours tops

Really depends on the game. For example a Platformer should grab you from the start. A Shooter probably after afew hours. An RPG probably 10+ hours in.

As an Example:
FF7 is one of my favourite JRPGs, i hated the start, but after getting into the world, i absolutely loved it.

I don't really recall deciding not to continue a game, aside from Bloodborne.
Usually what happens is I put them aside "temporarily" to play something else (often times a new release), and just end up never going back to them. This can happen even if I'm enjoying playing the game a lot.

I have forced myself to play through games some times even when I don't enjoy them. For example God of War 2018. This is one I probably would have backed out of, if not for the universal high praise it got, which made me think maybe I'll feel the same about it if I keep playing. (But I didn't). I ernjoyed the banter between the characters a lot, and the boss fights, but regular combat just had me going through the motions and wanting it to be over with.
