SEGA's released its revamp of Dreamcast favourite Sonic Adventure on Xbox Live Arcade.
The cost is 800 Microsoft Points (£6.85 / €9.60), and for that you'll get an HD, digitally remastered trip down memory lane. Little else has changed.
The PlayStation 3 version arrives next Wednesday, 22nd September for £6.29/€7.99.
SEGA has also revamped Crazy Taxi for XBLA and PSN. It's due this autumn, although no specific date is set - approval processes and that.
