For me, it's a combination of a couple of those options, including more not shown (belonging to 'Other' obviously).
First, the ones shown in the poll that I share the same boat with:
- 2 Procrastination/laziness/unmotivated
- 3 Decision paralysis - can’t decide what to play
- 4 Can't tear myself away from specific game(s)
For #2, I set Procrastination and Unmotivated in bold since they sometimes are the cause, but laziness per se not so much; that one is different to me (I.E. with actual laziness I think I wouldn't even bother browsing the Internet or even launch my games to start with). I do procrastinate on my currently-in-progress saves in various games, for some of them that is. But I am also unmotivated to continue in some cases as well, really is a mixture. The 'unmotivated' part usually kicks in if the last session I had of a game didn't have any "recent progress" made in it (usually it's a story-driven game affected by that issue, in my case anyway) that seemed to go anywhere (basically, if by that last-played point the story isn't interesting or I want to know the rest... I'll take a break and eventually forget about it due to lack of motivation to continue).
For #3, that one does happen from time to time. Example I can easily think of: I have Steam opened, while to my right the way things are placed in my room I have a desk (reaches about waist height when I stand up) which I've placed a bunch of retail game boxes on (and games in them of course) stacked next to each others and some piled up on top of each others too in a number of 'columns'. Sometimes I'll see my list of Steam games (there's about 60 installed, out of 300+), turn my head to the right and see my rows and piles of around 50+ games (some of them are PC games, some are Wii U; the only 'modern' console I have; the other games being some SNES and some for the Genesis as well; and none of that includes the NES and PS1 retail games I have stored in a separate desk in my room just about 3 meters behind me that aren't in my field of view).
Then, I have... let's say... Battle.net open as well, and occasionally on top of that my Origin (with about 12 games installed I believe) and/or my UPlay is opened (even though on that one I literally only have FC3 Blood Dragon installed for now). THEN... after that, I can just click a small shortcut I placed on my Taskbar that reveals a list of digitally-bought games from GoG that I can fire up at any moment I wish since they're almost all installed (that's 23 right now, out of about 26 or 27).
So why saying all this for point #3? Well... I. Cannot. Decide. Which. Game. To. Play., I sort of stare into the void at my monitor without much plan or purpose for a game; the "incentive" or the mood just refuses to kick in, I let go the few spare hours I have aaaaaaaaand the next thing I know ooops it's time to go do something else, or go out, or go to sleep or take a shower or eat something or whatever. Basically I "Miss my game time" by pretty much being paralyzed not knowing which one to start up because "Way too many to think about right now". I'm not sure if only ONE game installed would change anything since I can still just reach my Wii U, or stand up and go at the back of my room (well behind my chair) and go sit on my other chair that's facing my flat CRT TV on which I can play my retro games pretty much instantly (well I do have to pick one up and insert it... and power up the TV but that's just first world problems right?).
For #4, also happens from time to time. Been happening recently with Heroes of the Storm and my 'come back' to a properly modded, fully stable Skyrim that I'm enjoying the crap out of. I'd play them a bit too much, and regularly (at least one, if not more sessions every day) and just literally forget about any other games I could play for a week, or two... or even more. It also happened just late last year with Monster Hunter World. I LITERALLY just played that game and nothing else for about 8 or 9 days in a row. Then I managed to take a break away from it to play one or two others (Heroes of the Storm was calling at me, couldn't resist), then only to get back at it for another 6 or 7 days non-stop... took another short-lasting break for 1 or 2 days maybe... THEN... back at it for around another week and THEN I finally completed the campaign and got done with it since then.
And now, basically #5 being 'Other' from the list of choices in the poll. That one I'd say would need to be translated to "Simply a shitty ass game one after another", tainting my mood for playing a game that can last a bit too long sometimes (well, for me that's maybe 2 or 3 days at most without touching a single game; but I rarely get past the 3 days mark without gaming at all). Essentially, if I happen to be playing a new game I just got that ends up disappointing me (happens often, I'm WAY more picky at my age than I used to be when I didn't care in my youth if a game was rushed or was simply very bad because no time to care for critical analysis for them; so I ended up blissfully enjoying shitty games and have fond memories of them to this day) and leaving it only to end up buying (or newly-installing a game I had bought some time ago) another one with the SAME result... if that happens like two times in a row I basically get pissed, complain about today's state of video gaming in general in my head for about 2 days straight, get calmer by the 3rd day and forget about it by the 4th or 5th day and I'm back at gaming again.
And that's about it.
Now I could keep on going with this but I had to type something relatively quickly since I errr... I sort of have to go play Heroes of the Storm right now. Not sure why, I think it's because I like it still (despite complaining about totally valid points but whatever, it's still fun... overall... maybe, not sure; whatever I just play it... although I should really go back to my Witcher 3 saved game, but yeah... can't do right now I must play with Zagara and dominate my Lanes and throw Zergs at people, fun stuff).
