Oh, Gameloft. You repeated the same mistake Majesco made: You chose to reveal a new game via an E3 invite. As you can see above, the company is working on The Oregon Trail for DSiWare, which could possibly be a port of the company's iPhone game of the same name. You can bet we're planning on checking it out at the show.
Now, if you'll excuse us, we have to spend the rest of the time before E3 not dying of dysentery.
