I actually appreciate Greatest Hits titles, for several reasons:
1. If you're actually collecting GH variants (like I am) when you seperate them from the original releases on a shelf, you get the overall picture of what that particular system's audience was. The results are often quite amusing. For example:
Nintendo GH: Almost always all Nintendo quality games, with other big calibur games like RE4 and Baiton Kaitos.
PlayStationOne GH: Quality Games like FF7 and Crash Bandicoot sitting next to turds to Dukes of Hazzard and WCW Nitro...
2. Working retail, it's always an eye catcher. No less that 2 people every other day ask me what the difference between the GH box and the original are. When I explain what the GH means, the customer wants to know what they're missing out on. It may look sucky on a shelf, but it really helps drives sales.
3. If you push it even further, companies can get REALLY creative in their marketing. Microsoft now has the "Best of" Platinum Hits. $9.99 games going up against $19.99 games will suddenly get customers to look over at your cheaper prices. I've sold more CounterStrikes and Fuzion Frezy games than other titles in the GH category.
Now granted, some color choices may suck (bright yellow?) but I do like Microsoft's Silver, and the original PSone's green was a nice compliment to the black.
4. Greatest Hits make the original look even better. Case in point:
Had the Dragonball GT re-release had the GH banner, most collector's would not have cursed spending the $$$ on the original one when they can have the same black label re-release for $15.
