I looked up some background info on Hudson Soft's Hagane for the Super NES, which Wikipedia claims was available in the U.S. only at Blockbuster Video. Now, Wikipedia is what it is, and that tidbit about Hagane isn't sourced. Someone mentioned the rental thing in a thread last year, but there's no conclusive word on it.
The evidence for Hagane being rental-only: it's apparently very hard to find. The few copies on eBay run around $100 for a loose cart, and someone wants $2000 for a sealed game.
The evidence against: Hagane was advertised and reviewed in magazines a lot for a rental-only release. Many writeups, Wikipedia included, have other questionable Hagane facts. For example, they put the game's U.S. release in 1994 even though magazines didn't review or run ads for it until 1995.
So let's hear it. Does anyone remember buying Hagane (the Final Confict!) brand new at retail back in the mid-1990s? Or did Hudson, after advertising the game, get cold feet and ship it only to rental stores?
