No text-based games, all here are graphical and the top browser MMORPGs have excellent graphics. I am going to present to you this short list of all the best free browser MMORPGs that are very similar to RS.
RS is medieval Western fantasy, the 3D graphics are very good and it has tons of content. Have you ever played cheap runescape accounts then wondered why everything is dark brown and green? There is a daily player vs player tournament in Dragon Eternity. The best games like Runescape should also have great combat content. An active and passionate online community is a must for any MMO for it to succeed. It is more similar to RS.
Crystal Saga is much more colorful compared to RS or Drakensang Online but it’s just as fun.
