The world of Phantasy Star Online just got bigger.
Sega.com recently posted a server maintenance update on their Phantasy Star Online website. According to the update, the Japanese and US servers for PSO have been connected and you can now play on servers from either territory. So get out there, meet some new people, and have some PSO fun!
UPDATE: It appears that at this time, the servers are not linked together. Sega should have it up and working soon.
