Oh fuck off. All off the top of my head so I'm sure there is much more.
- Infamous 1/2/Festival of Blood
- Killzone 2/3
- Resistance 1/2/3
- Uncharted 1/2/3
- MGS4
- Demons Souls
- God of War 3/Ascension (Ascension is mid but 3 is great)
- Gran Turismo 5/6
- Motorstorm/Pacific Rift/Apocalypse
- MAG
- LittleBigPlanet 1/2
- Multiple Ratchet and Clanks
- Siren Blood Curse
- Starhawk
Most of those aren't available at all on any other platform outside of PS+ Streaming
Then you have smaller/niche titles like some of which never left the console
- Fat Princess
- Folklore
- Initial D
- Wangan Midnight
- Tokyo Jungle
- 3D Dot Game Heroes
Then we can add series that were exclusive to PS3 like Yakuza
Then we can add all of the HD Collections that brought amazing games like Ico/Shadow, MGS, Ratchet, Sly Cooper, 2 God of War collections.
THEN we can add the fact that it got the vast majority of third party games.
The PS3 beat the Xbox 360 in sales worldwide as well.
Edit: AND they had the best sports game during that era and to this day. MLB The Show.
I'm sure you will find all of this shit though while having not only a DK avatar but a DK avatar with a Xbox logo.
