Gamers like me and you should really know what happen to Japan. So how are we going to contribute and help? Well there is. Support the game or make donation. Although I haven't donate anything (will do so when my PayPal is ready), but knowing that Play-Asia is doing the part of the donation is really a two thumbs up. Anyway you can check out the list of games and accessories here and do your part. The list is growing so do check it out often. You can request for the item that you want too.
Here's the link again.
