Sony elected to reveal January's PS Plus games months ago, and that means that today's February lineup is the first in months. Coming to the PS4 is 'Transistor' (review here) and 'Apotheon,' which is debuting as a new title. On the PS3, there's 'Thief' (review here) and 'Yakuza 4.' On the Vita, there is 'Kick & Fennick.' Finally, as a cross-buy title for the PS4, PS3 and Vita is 'Rogue Legacy.'
With so many free games (and an interesting mix to boot) it seems like it's worth having PS Plus if just to enjoy the influx of free games every month. Users need to be sure to go download/add games to their accounts during the month.
