An interesting change in the Metal Gear Series. I believe you use cards right? It reminds me of Kingdom Hearts for the GBA. Since this game came out around the same time as the PSP was released, it shouldn't cost that much, and is indeed a classic. I don't own a PSP, so I really haven't gotten the chance to play this game much. However, when it did come out, I was considering getting this game along with the PSP.
