I've played a shit load of MMORPGs over the last week trying to find one I like. Only Guild wars 2 has done it for me. Never appreciated how fun Runescape was until I played WoW, ESO, etc which are just pointless grind quests.
Runescape gets a lot of shit but I honestly think it's the best sandbox mmo out there.
Not to mention the quests on other games are so bloody dull compared to Runescape ones. "Go speak to him, then her, then kill 5 crabs" with the only difference being level scaling lol.
