I've been playing RO on and off over the years and been through a number of both donation and non-donation servers. I'm 5 days old with DreamerRO and it surprised me: their organized/civilized society, their helpful players, the ease of levelling which makes hunting for items sooner, their great quest headgears (+7 all stats and slotted!), their moneybag system. I'm not a donator and prefer to hunt solo and all these things have given me high fun, high quality, game time.
