DS:ToA is by far the best hack and slash for the PSP. Totally recommended
Although any information about the game remained hidden for quite some time, the final result is surprisingly good and its well packed on the PSP.
Graphics- The graphics are pretty good. The character animations are well done and the world is nicely done. The framerate does drop a bit at times, but its really nothing that harms the gameplay.
Sound- Both soundtrack (reminds the other DS's) and ocasional voice acting are well done.
Gameplay- The controls needed to be changed drastically to fit the PSP, they take little learning though and are really good. The player does only control one character though.
Value- The single player mode is great and should keep you busy for hours, but the multi-player seems endless fun.
IF you are either an hack and slash fan or DS fan this game is totally recommended.
