I would like to see the asymmetrical maps fixed. Especially Hot Pockets, which gives an advantage to one player because of the initial positioning of the warmachines.
To all of the people complaining about Kongregate working on achievements and not new cards, you're completely right. But what all of you fail to realize is that Kongregate did not make Kongai, they simply contracted it out to someone else. So Kongregate adding badges to Kongai (which IMO should have been done a long time ago) does not affect or slow the development of new cards for Kongai, which are due early 2009. If you would like to take a look at the developer's website, go to Sirlin.net, including a forum with many good Kongai discussions/tips.

Kongai was actually made by David Sirlin of Sirlin.net, contracted by Kongregate. I would assume tip money for Kongai would go to him.
