Platinums 106 and 107
Platinum 106: Everybody's Gone to the Rapture
A good game with a beautiful soundtrack. I wish you could walk/run a little faster (holding R2 to walk a little faster), but was still a good game. Sadly the trophy list is kind of annoying. You have to play through the game at least twice (unless you know what to do and when to upload a save to download after) and the radio trophy was a pain in my backside. But, like I said, good game, though.
Platinum 107: Serious Sam 4.
A fun and easy platinum! I like the Serious Sam games for their cheesy comedy and lame one-liners. This one has by far the easiest trophy list out of all the other Serious Sam games on PlayStation (3: BFE on PS3 and the collection on PS4). Can be done pretty quickly too, if you blow through the game, as long as you remember to do the side objectives along the way. I took my time with it (played it co-op with my dad) and we got in done in about 20 hours.
