Launch is always a rough time and being seven years removed the memory will be foggy as to what we had a launch. So it's time for PlayStation, This Is Your Life!
PS4 (2013): COD: Ghosts, Angry Bird Star Wars, AC4, BF4, Blacklight, Contrast, DCUO, FIFA 14, Flower, Injustice, Just Dance 2014, Killzone: Shadow Fall, Knack, Lego Marvel, Madden 25, NBA 2K14, NFS Rivals, Resogun, Skylanders: Swap Force, Sound Shapes, Super Motherload, Warframe, Trine 2

I like consistency), Tiger Woods 07, Tony Hawk's Project 8, Untold Legends: Dark Kingdom.
Europe and Australia had a few more because it was released a few months later. Now get ready for the monster launch...
PS2 Launch (2000): Armored Core 2, DOA 2: Hardcore, Dynasty Warriors 2, ESPN Track & Field, ESPN Winter X Games Snowboarding, Eternal Ring, Evergrace (remember this game?), FantaVision, Gungriffon Blaze, Madden 2001, Midnight Club: Street Racing, Moto GP, NHL 2001, Orphen, Q-Ball, Ready 2 Rumble 2, Ridge Racer V, Silent Scope, Smuggler's Run, SSX, Street Fighter EX3, Summoner, Surfing H3O, Swing Away Golf, Tekken Tag, TimeSplitters, Unreal Tournament, Wild Wild Racing, X-Squad
Fewer titles for the Europe release, but it had some different ones thrown in.
PSX North American Launch (1995): Air Combat, Aquanut's Holiday, BATTLE ARENA TOSHINDEN, Jumping Flash, Kileak, NBA Jam TE, Rayman, Ridge Racer, SF: The Movie, Total Eclipse Turbo
Same case with Europe. PSX had nothing but Rayman, RR, NBA Jam, and Toshinden going on. The thing with the jump between PSX and PS2 was that multiplatform games weren't a big thing outside of maybe sports titles. By the time of the PS2-PS3 (sixth generation into seventh generation), generational multiplatforms were a regular thing so you needed something you couldn't find on the other.
...of course, that something was usually nothing special or nothing you haven't played before in a particular series and you could've honestly hung around in generation seven a little longer (or what Rock-et-Man...ROCKETMAN said).
