A $30 game free with a $50 subscription - now that's a nice setup. The deal only lasts until the 8th though, so get on it fast.
PlayStation Plus is a bit of a tricky proposition. You have to pay a monthly fee, but you get access to free games each month, discounts on other titles, and early access to demos. Whether that's worth $50 a year really depends on you.
Sony has sweetened the pot considerably though, and now there's little question about whether it's worth signing up for the service. If you sign up now and subscribe to a year of PlayStation Plus, you'll get the brand new Telltale title 'Jurassic Park: The Game' absolutely free.
It's a cool offer, but it's not going to last long. Sony is giving you until Tuesday the 8th to take advantage of this deal, so if you're going to jump on it, do it soon.
