Pour one out for Sonic Adventure, it’s time is finally up. It seems that Sonic Team are winding down the online updates for the game, which makes sense given that Sonic Adventure 2 is around the corner. Accessing the Sonic Adventure Online site (via the Dreamcast) presents a ‘FINAL UPDATE’, which states that World Rankings are closing. New times can still be uploaded, but no more contests or prizes. RIP, Sonic Adventure Online.
