Yes if you want to play tons of great games at a cheap price, PS3 is definitely the way to go. But you'd need at least a 500GB HDD, that's very important.
Many games on PS3 won't have any PS4 remastered treatment (and those are more expensive). Also recent models of PS3 (slim and after) are very sturdy consoles.
And finally, PS4 is still rather expensive IMO, it's a great console obviously with great exclusives, multi and indies, I enjoy mine, but I also really enjoy my PS3 that I still play regularly...and I play 99% of my PS3 games with a DS4 which works great and is better than the DS3. In my list I think only ICO and GT6 can't be played with a DS4.
Games on PS3 that I really, really enjoyed:
- TLOU & Left behind should be the first games you boot your PS3 with...
- Metal gear legacy collection (Don't skip Peace Walker, it's incredible, you could call The phantom Pain "Peace Walker 2 + open world", you can skip MGS4)
- ICO & Shadow of the colossus HD
- Infamous 1, 2 and 2.5 (incredible vampire DLC)
- Uncharted 1, 2 and 3
- Tomb Raider 2013
- Bioshock 1, 2 and Infinite
- Batman Arkham Asylum & arkham City
- Far Cry 3
- Grid 2
- GT5 or 6
- Rayman Legends & Origins
- Ni no kuni is really like a western Dragon Quest game from same guys who make most Dragon Quest games, so get it if you like Dragon quest RPG.
- Braid, limbo, Fez, Portal 2, Guacamelee
