In case you weren't following the unfortunate tragedy, the recent 8.9-magnitude earthquake in Japan has caused great devastation. If you want to help, here's your chance. SEGA and Capcom have dropped the prices of all Sonic titles and Street Fighter IV, respectively, on iOS devices and will be donating 100% of the profits to the Red Cross Disaster Relief fund in Japan.

The games are:

Sonic Spinball ($.99)

Sonic the Hedgehog ($1.99)

Sonic the Hedgehog 2 ($2.99)

Sonic the Hedgehog 4 Episode 1 ($3.99)

Street Fighter IV ($0.99).

The main steal, of course, is SFIV as it usually sells for $9.99 and it's a great port of the console version. It doesn't beat a gamepad or arcade stick, but for on-the-go Bluetooth-capable multiplayer it works wonderfully.

You guys buying any of the titles on sale? Sega's sale goes on until March 20th, and Capcom's until March 22nd.
