If Pokemon Go ENDED TODAY...

I would regret not being able to finish my gen 1 pokedex. That was the goal from the start and being so close, it would be frustrating to quit now.

I like a lot about my collection and would feel decently satisfied about many of my achievements. I'd wish I'd gotten the golden ace trainer when it was still possible and the golden fisherman when it was still easier.

EDIT: I'd also miss having a reason to walk. I'd start playing Ingress more but it isn't as engaging to me and doesn't reward random wandering at all like POGO does.

I'd be slightly annoyed. Maybe. Then I'd be able to clear out all my screenshots (that I'm terrible at getting rid of), uninstall Pokémon Go, and move on to a different game.

My collection is meh. It's not terrible, but I've not picked up too many decent ones. It works for me.

No particular regrets, though if I ended today I'd probably wish I had downloaded a scanner so I could know exactly what was around me. (Seriously, I look at my Nearby Pokémon screen and rarely see anything decent. I look at the free online scanner someone set up for my general area, and bam! Aron, Ralts, Abra, Hariyama, Slakoth, Treeko, all within walking distance. None on my scanner. How many times over the past 18 months did I look at my scanner, saw 9 Pidgeys, Ratattas, Nidoqueen's and Weedles and said "Meh, not worth going out." and missed something good because the Nearby list didn't show them?)

The only thing I wish I had done was to start looking at IV's early on, rather than after I hit level 20 or so. I took the advice that I should pretty much ignore any Pokémon before Level 20, and so I was getting rid of them without checking their Stats. I wonder if I tossed out any 100%'s in those early, stupid days?

I would feel very very relieved. Would be a present from heaven. Happens when you are sensitive to addictions

It would feel silly, because it became part of a life style. That said, when my phone was under repair for 2 weeks I did not miss it that much.
From 2012-2015 I played Need for Speed World. They closed the game and access to servers. It was much more fun and addictive to play, over time became really good, have in-game contacts etc. Built up a garage of customized cars and then it was all gone. I cherish the videos and screenshots I made :D Fortunately I spent less than $100 on it.

I would be immensely pissed, because I have an EX-invite for tomorrow and I still have hope for a high IV specimen.

But other than that, I like my collection a lot.

I don't regret much, maybe one or two transfers...

And I wish I had blown all my stardust.

They're my favourite thing.

I'd want at the very least to have everything that's not a regional. I'd also regret if Niantic does not make an app where you can at least see the mons you've captured, in an offline app, like a memory of it.

Would you feel satisfied? - Absofuckiknglutly
Do you like your collection of PocketMonsters? Yes
Any regrets? Playing this fucking bullshit game
Anything you wish you had done? Quit earlier
Do you like butterfly kisses? Never had one but i'm open to new things

Saving all those magnemite and murkrow candies without getting to their final form

My reply greatly depends on what this turns into when I press the button...

I would learn Swift and develop a better replacement game.

Main regret would be missing out on the legendary birds (was on hiatus then). At least I managed to complete my Gen 1 Dex except regionals and legendaries.

Despite my frustration with the current gym system, PoGo has been the source of many great memories, plus exercise and socialising.
