Seems like one of those things everyone would say in the abstract, particularly on a survey. Then when the studios go for safe projects and the thing they remake is among someone's personal favorites they'll watch it anyway, validating the strategy.
The amount of remasters of once original successful games is increasing by the year.
There's also a pretty substantial incentive there in terms of new market access, by releasing old games on new consoles, and less work overall. A better comparison in that regard, for most movies, would probably be re-releases, with original film remastering and DVD extras.
