Mabinogi
DDO
RoM
LotR
Vindictus (if you are NA)
i forgot some...but these are the top games of f2p.
Community wise..i would say you should try mabi because the community is very nice.
DDO is good if you know some people there + it depends on your time-zone..
LotR community is good too
Vindictus Community is smiliar to Mabis
