Well I have played Zantarni in the past but it's quite hard to get the items and etcetera.

Roliana is easy and fun to play, nice community. You can donate $1 for 1 platinum which it's worth up to 2k (and their most expensive item there is probably 20 - 30k) catch my drift ;D

I'm only attracted to the ones with good activity and pixel art so I'd choose Roliana and Menewsha.

Kinsaki also looks great but last time I was on it today, there's like 10 people online
