Before he was making games about historical pinball battles and sarcastic fish monsters, Vivarium's Yoot Saito created a skyscraper-building game called SimTower. He put the same kind of quirky, bizarre charm into what seems like a run-of-the-mill Sim game as he did Seaman, leading to a game in which you can read every resident's thoughts as they ride elevators.
Saito followed SimTower with a PC sequel called Yoot Tower, and a Game Boy Advance version called The Tower SP that, sadly, didn't get released until 2006. Now, according to a blog post, he's working on a version for a current system -- the DS. The Tower's vertical orientation is a perfect match for the DS's unique aspect ratio, we think. He's hoping to have the game out before summer.
