For Those Who Don't understand what I mean an "In-Game Trade" is a trade made with a non-player character within the course of a main series Pokemon game...anyway I have..I traded a Casey/Abra for a Barrierd/Mr.Mime..but in many of the english games,they give their pokemon certain nicknames that don't really appeal to me,so I've done it once,but I've never done it again after that.,aye,I'd rather get the Pokemon myself and give it a nickname I like. instead of trading a perfectly good Pokemon.:p

Only for pokemon that weren't catchable that game

Many times like, for instance, Rotom for ditto in Pokemon black.
