Sony just recently announced the PS1 Classic, a move similar to what Nintendo did with its NES & SNES Classics. Coming out in the next December. Here's the announcement video:

The decive will come with 20 pre-installed games. Some of them are already announced:
- Final Fantasy VII
- Jumping Flash
- Ridge Racer 4
- Tekken 3
- Wild Arms

So many #RetroGaming players thinking whether to buy this device, have their wishes for the remaining 15 games. Those are what will make or break the success of the system. So it's better for sony to choose their games carefully (I know they did but...) to leave the least amount of its audience in sour mood after the final announcement.
We all know how many people are hurt by not having Chrono Trigger in the SNES classic, since it's semi-globally known as the best game for the system.
Remaining Games
So what I think must be some of the remaining games? I gave it a thought while looking at all the games released for the system. Those are my choices based on their variety and popularity in the list of best selling games:
- Castlevania - Symphony of the Night
- Crash Bandicoot
- Final Fantasy Tactics
- MegaMan X4 or X5
- Metal Gear Soild
- Rayman
- Resident Evil (Any, but for timing, I think RE2 would be the best.)
- Spider-man
- Spyro: Year of the Dragon
- Syphon Filter
- Titres Plus
- Tomb Raider
- Tony Hawk's Pro Skater 3
- XenoGears
- Any Soccer/Football game. (They're endlessly replayable.)
I think Crash, Metal gear Solid, Syphon Filter, Castlevania and any Resiedent Evil.
And those games that aren't popular but I'd like to see in the system:
- Breath of Fire III/IV
- Chrono Trigger/Chrono Cross (Any of those might be the seller for me.)
- Driver 2 (Amazing for its time)
- Dino Crisis (Plays the same as Resident Evil but better for me. I don't think we'll have both.)
- Final Fantasy Origins or Chronicles (to compare with VII)
- Monster Rancher 2 (I'd like to see what happens when you change virtual disk.)
- Parasite Eve (Popular but I don't think it'll have a chance, I haven't played it yet so I put it here.)
- Silent Hill (Amazing game but I'm not sure about being in PSClassic)
- Any Disney game: The Lion King, The Little Mermaid and 102 dalmatians all were great in my childhood. But not much replayability value.
Features

Now some features that will add to the system, since we already know that it will have HDMI output:
1) Instant Loading Time:
Today technology can certainly make that possible even for cheap. If you don't have this feature you're losing to emulators on the weaker side of Android systems. Loading times were one of the most frustrating things the PlayStation 1 generation had to deal with!
The option to control the loading time, would be a great option to have for those who want to feel the most of what PS1 felt like.
2) Save States:
I think "save anywhere feature" may ruin the experience. But we live at an age where if you don't have save states you have to compete with every game that has that feature.
For me even "suspend anywhere." feature will do the job (save deleted after resuming) but for others... I'm not really sure.
3) Changeable Display Options:
I hope they keep the aspect ratio at 4:3, but I'd like that the 3D games can change/upscale their resolution (and 3D rendering) from the native PS1 resolution.
SNES Classic had the option to CRT filter, or have Sharp Image/Pixel Perfect. and I hope #PlayStation Classic comes with similar ones. If sony want us to cheer, have even more than that!
The filters of SNES Classic
This alone will make the game feel fresh (Compare the look of FFVII PS1 & PC versions.) It's not hard to do but also not easy to do for 20 different games.
4) Other things:
I'd like a Dual Shock Controller, they may sell it seperately. Because I loved it more than the classic one.
One feature I think will be amazing but probably we won't have are "Fast-forward" & "Slow-down" Buttons. With games as Grindy as FFVII in the list this can help make the game less frustrating for the new generation.
"Yeah, 10 Seconds is a long time."
Of course, most of those will probably wait for FFVII:Remake on PS4, but let me be optimistic.
What do you think?
These things will make me excited for this new gaming system, but I don't think I'll get a PS1 Classics as I have more pressing priorites. But The Playstation Classic Really have potential. This is coming from someone who grew up with the original Playstation every summer.
