I have more than enough to purchase them all, but I think I'm going to stagger the purchases to make myself feel better about spending the money.
Also, whilst the subject of anime is all up in this grill. I've finished the anime list and ranked it all, I just need to finish putting my thoughts into each one. I've done a few but not many. I'll probably type up all of my best rated animes first to give a good indication as to why I loved them, after that will probably go down to what I can remember xD
