If you want to play any games from the Universe series online, you're only options will be (after the 360 server closes):
- Phantasy Star Universe (PC), free online (Japanese only)
- Phantasy Star Portable 2 (PSP) (available in English)
- Phantasy Star Portable 2 Infinity (PSP) (Japanese only)

I know it's a sad time. At least we will ALWAYS have the option of using the PSP versions to play online (though tunneling software like XlinkKai) once all the servers go down.
