Recommend me some old IPs PS3 games

[j.thomaz]

hi, I'm only considering for the moment to buy a ps3. Can you guys suggest me some good games on from old ips (16bits era) for a retro gaming enthusiast looking to expand his relationship with old series?

Example: 

-Sonic 4 episodes 1&2 (evident one)

- alien isolation ('cause alien, da)

 

many thanks.
