Online shooter MAG is already available cheaply in the Greatest Hits range, but if you're still not convinced it's worth the money then perhaps a PlayStation Plus-exclusive free game trial will help twist your arm.
Subscribers to Sony's premium service will be able to play the game for free, with full Move support. You'll only be able to advance to level 8, at which point you unlock the game's gloriously chaotic 256-man Domination mode. Even if you keep playing, you'll continue to accumulate experience which will then go towards your character in the complete game, available to buy on download for $29.99.
Our MAG review shoots from the hip so be sure to read it for the full lowdown.
