The changes are actually trivial, (though they may seem to be a big deal to some.)
Well it's only natural we'll be focusing on those changes, they stick out like a sore thumb when everything else remains more or less the same
I believe most players complain because of the amount of time they invested
You're probably right on initial gut reactions to changes. We've invested time (for some people money as well) and gotten used to things being a certain way.
But I do think it also has other factors at play that contribute to those reactions. One of those reasons being how long you can sustain interest in a single game for an extended length of time and not grow tired or bored of it. Particularly if you're playing multiple instances of that game simultaneously
Another of those reasons being players want to achieve completion the first time on a buildings initial release, not the second or third time round. By the second or third time you may have lost interest in the current game you're playing anyway, and therefore never complete it.
The only way you wouldn't have this sort of reaction is if everyone makes a conscious decision to not stress about whether they complete the building during an Event, accept the result each time, and use subsequent Events if they're still playing to fill in the remaining missing Upgrades
Well the gamers leaving the game due to the changes has started. I just lost a major player in my guild due to Inno’s greed.
I’ve been playing for 4 years ( the longest time I’ve ever played a stupid online game,
Think about that second statement for a moment, and then look at your first statement. How long had those gamers that left been playing Forge for?
If they stayed engaged for +/- 4 years as well.... and if they also stayed far longer than they have in any other game..... then regardless of what role any decisions InnoGames made plays in their decision to leave now (as opposed to leaving later on), it's probably also got a lot to do with playing the same game for +/- 4 years no matter what that game is or what changes occurred during that time
To put it another way, if absolutely nothing ever changed in the game would anyone still be playing this game after 4 years? If yes how long would you expect anyone to stick around for? 5 years? 10 years? Their entire lives?
I definitely would have liked the recent changes to have been done differently, on the basis of what I would believe to have a lower rate of short and long term player retention decay, but the real test on those changes will be how long new players stick around compared to the already established players. It's unrealistic to expect people to never leave
