The AFK kick timer was what ruined the game.
On a serious note though, super interesting thread and really good discussion for once :o I don't think Sinnoh will revive the game. It'll definitely cause a huge spike in new and returning players the same way Unova did, but it'd also go back to being dead the same way. I think more endgame features for casual non-PvP play would keep more people interested in doing more than just afk because honestly, I can't seem to find a single reason to motivate myself to grind anymore, and most of the friends I talk to say the same, where they kinda start on a grind and then just give up. The same old grinding methods get boring after a while, even when you're just going by muscle memory, but a variety of things to do by yourself or with friends that you'd need to grind for makes it more bearable. What do we have for now?
1. PvP (OU matchmaking and events),
2. PvE events (99% catching contests, 2 a week on average, which is a good number),
3. PvP (with absolutely no argued reason why an untradeable shiny prize has to be 4x25 and not even 4x28), oh wait I already said PvP
3. Shiny hunting,
4. AFK
and it's been that way ever since I joined the game and before that too.
I keep trying to log in from time to time and do something, but I end up just chatting for a bit, telling everyone I miss them, getting distracted and eventually AFK kicked, and trying again in a month.
No uguu though, I love this game for some reason. Or is this Stockholm Syndrome?
