How long have you been playing? Evidently not very long judging from your post. I've been playing from the year Grepolis was created and there has been many things added since its inception. It's called Progression. If Grepolis stayed the same then it would lose players. As time goes on, Grepolis will add even more changes. I was not happy about the upgrade to the 2.0 at that time, but now that I adjusted to it, I can't see myself playing the old version. Notice I said, "I adjusted to it". So I would advise us all to adjust to this new change and anticipate the upcoming changes because they will come. Stop whining and start winning!
While I agree with the spirit of your post... I can't help wonder if there is validity to the comparision...
Comparing the 2.0 changes (which were designed to heighten the gaming experience) to a security feature (which while effective against cheaters... is nothing but an annoyance to legit players)... is a stretch at best.
Players "adjusted" to the 2.0 system and found fun in it... because that was the point of the 2.0 software. Game enhancements.
For the captchas... there is no fun to be found... except maybe for those gamers who enjoy remedial math.
The simple truth is, Grepolian gamers just need to put up with this security feature.... or find a different game to play.
As for other changes, you are correct. The Innogames company will continue to make changes that their management team deems best for the future profit of the company.
As the players of that game... and the customers of that company... its important that we give our feedback... both positive or negative... to help the management make the best business decisions.
In the end, if the company choses a path we don't like... and creates a game we no longer enjoy... we simply need to take our gaming... and our business... elsewhere.
