I used to play Runescape a lot, but after they removed free trade and wilderness I quit. It's no longer the game I once enjoyed now, with rife microtransactions.
MMORPGs seem to be on a decline in general. The only one I currently play at a casual level is Wakfu, which is pretty unique amongst MMORPG as it is turn-based strategy much like the old Final Fantasy games, instead of mindless button mashing which many MMORPGs have devolved into.
