I'll be honest, I've only played a few. The two games I played the most of were Phantasy Star Portable 1 & 2. Of them I probably only really got into the first and grinded out most of the second game as fast as possible. I've played a bit of Phantasy Star Online 2, but I couldn't really get into it because the translation patch was really bad. I understand its difficult for games to be translated, especially MMOs which are constantly having content added to them.
Have you tried the the SEA server? The client there is already in English, you won't need to apply individual patches unlike in the JP server. Learning the movements maybe a little difficult at first but once you've gotten the hang of it you'll enjoy it specially the daily events.
