Then 3E, with it's obsessive need to balance everything, ramped up the suggestions for exactly how much power wish had, by comparing it to what level of other spells it could cast. It essentially turned wish into a stronger form of anyspell. Questions of flavor were tossed aside in favor of making sure it was ABSOLUTELY BALANCED, and now 4E, which seems to be geared to making sure every last single thing is tested, tweaked, and market-researched to be "fun," has taken that to its logical conclusion and just thrown the spell out entirely.
