And to answer your question:
Yes, it completely depends on the game and how that game was created.
A small game may run on anything, but the more functions and data it requires the more critical the hardware becomes.
For example, parallax maps need about 2000 times the RAM as tileset maps - if you use only tilesets, you'll be able to do much larger games than if every map is a parallaxed map - and the larger the parallax, the more problematic that is.
A game that needs a lot of parallel process also needs a lot of CPU power to prevent lag
And so on - you can only test each game, you can't give a minimum for all games.
