So I loved playing beta this weekend btw, and I noticed that they are implementing an emote system pretty similar to most mmo's. The whole /sit /dance etc etc... but I noticed there are also /lute /flute /drum and so forth- INSTRUMENTS!!!! This immediately brought me back to my time playing LOTRO, and in LOTRO there was a comprehensive player music system, which sprouted forth into entire communities of players forming bands and gatherings of in game music lovers and songwriters. It is in fact my belief that this music system is one of the most potent lines of life blood that LOTRO has left.
But.... ESO is now in the position in which they can take that >
The suggestion I throw forth then is obvious by now, I feel that mimicking or even improving on the idea of a player music system would be a relatively simple addition to the game. But one that I assure you would keep players returning to ESO long after its time has passed.
