Mafia Farm may technically be a modern game, but its plays like a mash-up of two of Facebook's oldest genres. It's FarmVille meets Mafia Wars, only it's not as interesting as either. And it's not because the two genres don't play well with one another, as the seemingly strange blend works well enough. It's that the elements of the game feel both archaic and unoriginal, with little in the way of fresh ideas.
The art of the remix is a precarious one. While a successful remix can make you look at the original piece of music in a whole new light, fail to treat the source material with enough respect and you'll be left with an inferior tune. Tetra Defense remixes and embellishes Tetra3D's block dropping formula, but loses sight of that game's core strengths.
