You really twist the facts to support your narrative.
1- Sonys SuckerPunch released two games on PS3 also 2 games on PS4 
2- Sonys Naughty Dog released 4 games on PS3, 4 games on PS4. 
3- Sonys Guerrilla released 2 games on PS3 and 3 games on PS4
4- Sonys Media Molecule released 5 games on PS3 and 3 games on PS4.
So
13 for PS3
12 for PS4
LOL big difference. 
GT7 being dog crap is all PD all Kaz, Sonys the same quality game driven greedy ass company they been since ALWAYS like all corporations are.  We are just fools parting with our money to them.

Sony Had EVERYTHING under one roof on the ps3. Open World games , linear adventure , online military shooters , Sci Fi shooters ,Creative games , Indie games , sim and arcade racers, car combat , flying games , hack and slash .  
And many if not most had GOOD reveiws . In fact the ps3 games with Ps4 sequals had BETTER reveiws. Not a Single ps4 sequal IMO is better than the ps3 counter parts except for garnturismo oddly.  5 and 6 were flawed as much as i enjoyed them and defended them , GT sport just did everything better minus the tuning and GT mode.
