i've played it for several hundred hours as a solo player and it's a blast. the biggest thing you'll be dealing with is storage space. there's also not really much need to do any of the daily stuff or events until you're an appropriate level, but don't let it stop you. overall just have a good time! it's a much better game than i ever expected it to be.
