If I have to watch an ad within 30 seconds of opening a game (not click on an ad, but it just pops up), I instantly uninstall and rate the game a 1 star. There is no reason to have an ad that quick. I can't even tell if I'll like the game or not, and an ad that quick usually means that there will be a ton of ads and that will drive me nuts. I definitely don't recommend this game because of that.
