I submitted a game about a week ago. Normally it takes around two days as far as I remember.
It differs between 2 days, and two weeks. Sometimes even more around Essen, when there are many new releases.
Does it take longer time to get a new checked by a moderator now because of summer or something, or should I perhaps submit it again?
Take a look at the pending games queue. It's quite long at the moment - around 240 games. So it can take a while. You can check the queue if you submission is listed; if yes, just wait.
