I'm only counting games with more than 1 release and of course Batman isn't a new intellectual property so I'll count
1. Uncharted: Super fun to just play through these games every few months. I've platinumed them all but going back on easy is a blast just to enjoy the story and set pieces again, especially 3 which is the best by a good margin imo

2. Infamous: I've enjoyed all 3 but the 2 on PS3 are my favorites. It's really hard to pick between them but the original, while not the greatest graphics wise or even gameplay, has a great sense of progression and I just like the feel of empire with its enemy types more.

3. Resistance: I honestly loved all 3 of these games for different reasons.
-The first was a great launch title with a fun single player and bucked many of the trends of modern shooters that I hate (regen health and 2 weapon limit).
-2 was a disappointing SP though it did have a GREAT moment when Capelli says "if you don't get past that door the whole F***ing human race is extinct. FIND A WAY!!!" I was legit freaking haha. The co-op is honestly one of the BEST co-op modes I've ever played with the different classes meshing really well and the competitive was fun as well with hectic battles sometimes just turning into death valley in some of the narrow points which was a blast personally.
-3 is a masterpiece. It's my favorite FPS of all time and I just love the weapon wheel, health packs, INVENTIVE weapons (freeze ray, atomizer, germ gun, turret shooting rifle, different grenades, and the list goes on), UPGRADING weapons like R&C which was just AWESOME and of course the story and graphics and PACING were top notch. Sometimes the quietest moments were the best and the valleys really made the peaks all the better. Also the set-pieces rivaled the best of Uncharted.

4. LBP: Come on who doesn't love the fun of sack boy? Great MP fun and the LEVELS that people create are so staggeringly creative it's just amazing. I love going on every once in a while and just checking the top rated for the week or month or I'll just go on during a big holiday and have all those great themed levels for Halloween or Christmas. Endless fun and I'll be getting LBP3 for Christmas this year with all 8 MILLION levels in 1080p!

5. ME: Great story and absolutely your decisions mattered...until the end, but that doesn't hurt the rest of the series which was fantastic

6. AC: Let's not forget the series that has been one of the most prevalent this gen.  I've beaten them all and platinumed 2.  It's a love hate relationship as I loved 2, Brotherhood, and 4 yet hated 1, Revelations, and 3.  The bad doesn't wipe out the good though because I still enjoyed 3 great games this gen so it gets a mention here.  Also it did a great job ending Altair's and Ezio's stories in Revelations.  The last cutscenes with those 2 were legit tear-jerkers and of course the side missions with Ezio's first love were great as well.
