I'm not sure how it is that Kairosoft does it, but they've managed to nail a gameplay formula that's so engrossing that seemingly everyone is more than willing to overlook the fact that all of their games are mediocre ports of feature phone games. I, for one, don't care at all, and have spent an embarrassing amount of time building game studios, racing teams, shopping malls, schools, and all the other things the guys from Kairosoft have put me in charge of.
For a limited time, Grand Prix Story [99¢] and Mega Mall Story [$1.99] are on sale. As you probably guessed by the title, in Mega Mall Story you manage a shopping mall. We explain how it all works in details in our review. Similarly, our review of Grand Prix Story goes over all the ins and outs of your racing career.
My favorite Kairosoft game is still Game Dev Story [$3.99] and I really recommend diving into that first if you've yet to play a Kairosoft title as its premise is likely the most familiar to readers of TouchArcade. Regardless, all the games are tons of fun (although some are more confusing than others) and you really can't go wrong with any of them.
