"Chrono Trigger (for the Playstation) may just be the Super Nintendo version with animated cutscenes added, but every item, skill, coin, and experience point carried over. Characters have to be re-recruited but playing over-powered characters allows interesting alternate-endings to be unlocked. Chrono Trigger is attributed with being the game that started "new game plus"."
"The second game of the series with some of the most memorable characters, introduced the concept of "leveling up" weapons in addition to health. All weapons, health, and ship upgrades carried over into the challenge mode."
"Third in the series, the polish on the weapons and the rpg elements really begins to shine. Carrying on the best of "Going Commando", all weapons, health, and non-story items can be carried over into "Challenge Mode" where enemies are stronger but this time ammunition is easier to come by and the weapons can keep up."
"Characters have to be re-recruited in successive play-throughs, but will retain their levels, skills, and weapon level from previous runs. Skill points, runes, and gold is also carried from one game to the next."
"Money and 'EP' for purchasing pilot skills carries through successive plays. Unfortunately: equipment and skills reset each time, though at least you receive EP back for skills purchased and money back for the parts."
"The first Final Fantasy game to have a "New Game Plus" feature, allowing items and 'orbs' (classes) to be brought into replays. Sidequest progress was also tracked, so missed NPCs and adventures could be done on later plays to get the perfect ending. Plays very differently from other FF games, but taken on its own still a solid game."
"Experience, money, weapons, and items carry over from play to play. Being able to keep Strike Expands makes getting Ring Perfects much easier and fun, and there's a lot of customize-ability to enhance gameplay."
"Characters, money, weapons, and other items acquired from previous plays can be brought into successive play-throughs. Includes the bonus of being able to choose the Japanese dub from the start, but leveling to unlock everything is very tedious."
"Items, equipment (except elemental-enchanted and some Holy Artifacts), money, and the bestiary are carried straight over. Most skills are kept, though some have to be "re-bought" they typically return with upgrades (like Fleetfoot automatically returning Counter Dodge)."
