Good job with the new games.

I did this with a lot of my games awhile back to redo the way I did attributions, correct some errors, and in a few cases to change backgrounds. (And there were a few I accidentally deleted, too.)

I didn't get any negative comments about doing that, and suspect you won't either.

But it does delete the highscores, so that's not good. I didn't realize it at the time, but that could've temporarily demoted people from say, Grand Master to Master status. But as we don't have that kind of rating right now, it may be less of a concern.

There are other games (not yours) that I wish would get the same treatment from their authors. What you've done is to take good games and make them better. There are some games that are fair or poor that could benefit from revision.

And there are still a few of mine I think about redoing sometimes...

A suggestion, niklas. What if you left the old game still intact, redid your background and added your features that are new and call it something new like "The Cities of Oceania Reformulated with South Pacific Breezes." Place a message with the old game to direct people to the new and improved one. People have a one in six chance of playing an excellent "Niklas Game" every time they play. You could increase the odds to one in three. Big companies have been reformulating their products for years. If perfume came in a beer bottle, I doubt if it would sell!
