I've tried playing Lord of the Rings Online, and it's kind of fun, it's not really different from other Mmorpg's (GW1 is alot better ofc), though it has BEAUTIFULL graphics.
When playing the game, I found out you can play instruments.
Like, you equip an instrument, type /music and you use your hotkeys (1-8 (you can use shift and ctrl to play higher or lower notes)) to play on the instrument. Altough it's slightly buggy with the timing (sometimes the note comes a bit later than you press the button (might be lagg though)), it's REALLY fun, I've learned to play Ode to Joy and the Imperial March on it! You could even form a band!
But I'm not here to talk about Lotro, I'm here to ask Arenanet to put this feature in GW2.
Here are some great examples:
Not awesome? Imagine a charr playing Titanic on a harp. There you go!
