Getting free swag and gifts with games is always fun. I like t-shirts as much as the next guy. But when swag shows up at the office that is actually useful…well, that is certainly a cause for celebration. Take today’s arrival of Custom Robo Arena for the Nintendo DS. Nintendo saw fit to include this nifty oversized key chain, which transforms into a handy screwdriver set. Just think of all of the things I could fix around the house if, well, I knew what I was doing.
