If you're not the biggest fan of strategic games but would like to try one out, PS Plus Premium has you covered. Sony just released a two-hour game trial for Tactics Ogre: Reborn, a remaster of the 2010 remake of the tactics JRPG title that initially came out in 1995 for the Super Famicom.
Two hours isn't long as Tactics Ogre Reborn comes from a different time. Beating the main storyline will take you around 55 hours, so two hours is barely 4% of the gameplay. But, Tactics Ogre: Reborn isn't exactly the type of game that takes a long time to get going. An hour or two should be enough to help you decide if it's for you.
It's difficult to justify getting PS Plus Premium (or Deluxe, in certain territories) over PS Plus Extra. The bulk of the best additions are available on the Extra tier. The only advantage of the Premium tier is having access to a growing catalogue of PSP, PS2, and PS3 titles as well as time-limited trials, like the one for Tactics Ogre: Reborn. However, the trials lack focus, to say the least.
You'd expect Sony to strike a bargain with companies to have their incoming games available for a one- or two-hour trial but that hasn't happened yet.
