I've been looking for a midrate Renewal server to play RO on again, and TrifectaRO is a really good one! It has all the convenient features I've come to look for in private servers - the only downside at the moment is that the population is pretty low (hence the low economy and quiet towns), but I don't mind it as much as I'm used to playing solo. So far I've had a really enjoyable experience, and the few people I have run into are super friendly! Hope this server gets more people soon :)

GatheringRO is a wonderful server with helpful people, both in the GMs and the players - I am constantly impressed by the reworking and improvement of current assets, and the server itself has everything I'm looking for in a private server. As an RO veteran (both on official and private servers), I find myself being unable to let go despite my preference for midrate servers! GatheringRO is a super enjoyable RO experience - hopefully more players come and see for themselves!
