Maxis chief Lucy Bradshaw has said that "core problem" with simply getting in to play Sim City is just about fixed, while crashes have also been reduced by 92 per cent from day one.
Last night a few European servers were switched offline in order to be upgraded, however all of the other issues seem to be clearing up with complaints becoming less frequent around the internet.
"I had hoped to issue an 'All-Clear' tonight, but there are still some elements coming together," Bradshaw said. "Maxis needs a few more days of data before it can claim the problem is completely solved and the game is running "100 per cent".
"The confidence our fans have shown is truly humbling," Bradshaw went on to say.
"I can't begin to explain the way a development team feels when something you're proud of is threatened at launch. Our biggest fear was that people who love this franchise would be scared off by bad reviews about the connectivity issues.
"But you put your faith in us. You bought the game with the understanding that we'd quickly fix the server issues. For that support - that incredible commitment from our fans - we are deeply grateful.
"As the general manager of Maxis, I want you to know that we cherish your faith in us, and the love you've shown for this franchise.
To make up for the problems Maxis has promised everyone who has already activate the game before March 18 a free download from the EA back catalogue. Details are to be emailed to those people who are eligible soon.
