It's a fun game but it got boring at around lv20 or so. It became repetitive quickly for the same reason PSO1 got boring for most. While it became a guilty pleasure for Phantasy Star Online, in Phantasy Star Online 2, it became tedious. You HAVE to walk everywhere. It's not like following a straightforward route and bam--boss. All of the emergency codes (special emergency missions which you have to complete to get a good grade on the runs) become obnoxious especially if you're farming and/or grinding.
I am interested in how they have the chat system in this version. I hope they incorporate a keyboard on the screen which you can touch and type like on a phone. That chat system in Phantasy Star Portable 2 was atrocious.
