If you're not yet convinced that PlayStation Plus is still the best deal going in gaming, Sony is giving you more reason to jump aboard the bandwagon. Beginning in January, Sony is adding three of 2013's biggest titles to its roster of PlayStation Plus games available as part of the service's Instant Game Collection. Included will be the latest instalment in the BioShock franchise, BioShock Infinite, the reboot of a beloved franchise in DmC: Devil May Cry, and Starbreeze Stdios hit Brothers: A Tale of Two Sons. On the PlayStation 4, gamers can look forward to Don't Starve, while Vita owners will get Worms: Battle Island and Smart, a trivia game we've never heard of. Sure, the offerings on the PS4 and Vita aren't as awesome as those for the PS3, but considering they're free with a subscription you've got anyway, free is free, right? With vouchers for the gaming service often going at a steep discount, PlayStation Plus is, without a doubt, the best gaming deal you'll find anywhere in the mainstream.
