but ..... please , you can't say it's better now than before !!!
There are gazillions of games using similar notations. There are many games, some of us even ours (Metin2 for example comes to mind), where players themselves count in k, kk, kkk in the markets when trading items etc. k, kk, kkk is not exactly unknown to gamers in general, albeit obviously unusual and unknown to Ikariam players.
With constantly growing numbers in Ikariam a change to a different numeral notation and handling was ultimately necessary. Many games solve too high number growth with a number squish, but somehow I think, Ikariam players wouldn't love the idea much of their 5.000.000 gold suddenly becoming 500 gold (prices would of course also shrink, every number would simply be squished).
k, kk, kkk is a mathematical notation that's universally known and used in maths etc., so that also doesn't change with localization, which is another problem that existed. Turkish for example had an expression for million that was, for some reason, even longer than the word million. In the US, a billion is something different than in the EU. There are many, many good reasons not to use words but simple units that are universally the same.
Sure, we could have also used exponential notation, then 1.000.000 would have been 1x106. The fact remains: with the ever growing numbers in Ikariam, this needed shortening AND a universal notation that doesn't change with language.
As always: we'll gather feedback and see what happens. I am not going to go into panic mode after not even a full 24 hours of the thing being live and in total not even 50 unique users mentioning dislike. We don't make decisions based on panic mode, we gather feedback, evaluate and then work with a more rounded foundation of feedback.
