The list author says: "I looked for a guide like this and couldn't find it. So here you are, the worthwile PSP tactical and dunegon-type games. The higher on the list, the more I liked it. Some of these are reprints. I only advise buying a reprinted game if you haven't played the original, none of the reprints has enough new content to justify the re-purchase of the same game. Also the best Japanese-only PSP reprint is Suikoiden I+II, unforgivably not available in English. There are more than 40 RPG's for the PSP. Don't buy Warriors of the Lost Empire (bad game, won't fit on list). Additional games (still unreleased) are Persona (good reprint PS1) and Silverfall (meh PC reprinted diablo clone)."
"There are a bunch of monster hunter strategy hack and slash games for the PSP. It's like a quest game where you hunt mythical beasts. The franchise has identical gaming experiences, worth buying one, but not all. This latest one is the best value in terms of 'extras.'"
