You cannot go wrong with Parasite eve (1 and 2), Digimon World 3, and Crash Bash (better with friend though)

You have a PS4 by the look of things, get Oldworld New'n'tasty rathter than the PS1 original. The game deserves the new gen support.

I never said I don't like challenging games.  I'm just not in the mood for one right now after beating TLoU on Survivor lol.  I go through spurts.  You can check SolidSnake91192 and see that I have the platinum in Demon's Souls and after that I didn't want challenge for awhile.  Also the challenge in most PS1 platformers is clunkiness lol

I have played all the Crash games but only really think 3 holds up.  Only played air attack so no on the others.  Beat Rayman 1 and 2.  Never really liked worms.  Thanks for the Hercules info think I'll pick that up digital (hard to keep CD cases around anymore lol).  What RPGs would be good for an RPG casual?  I always wanted to try those Final Fantasies due to the hype but they always seemed too time consuming (not a problem for the next couple months as I'll be waiting till Black Friday for everything other than free Driveclub) and too hardcore for me.

Played them both too lol.  I'll update the OP sorry guys it's been awhile

I have 29 PS1 classics. Most were 99 cents, or given to me free via Sony for various reasons... Although, as I've said... I get bored pretty easily. personally, since most of the games I bought were 99 cents, I wouldn't dare pay more than 2.50 for any of them unless I just didn't feel like waiting.

I think Megaman X4 is good for platforming. It's not too difficult, and is even possible to beat without getting hit/not using boss weaknesses. Personally, I don't like using boss weaknesses, and with zero, I've made it to the final weapon without using a single weakness. Don't really care much for getting through without getting hit, though.

Megaman X5 is recently released. However, I didn't buy it because I own the disc... X4 was stolen.

With X5, you lose anime scenes. But, also gone is the bad voice acting. I can't remember what X sounds like in X5, but my gut is telling me it's the japanese voice over. But, none of the characters shout when dying.

Anyway, as for the game itself, it's fun, it's challenging. It just has a few annoyances here, and there, but worthy of being a sequel to X4 and is still playable.

Resident Evil 2: Needs no explanation. Beat it 4 times on vita.
Wild Arms: Classic RPG, that I never knew about, and never would have tried if Sony hadn't given it to me free.
Wild Arms 2: A fun sequel, but, due to me not having much fun with games recently, I stopped playing it.
Dino Crisis 2: I bought it because it was 99 cents, and it looked interesting.. I hadn't actually played it yet.
Dino Crosis: Bought this several years ago when it was on sale. A resident evil with Dinosaurs. Not quite like the second.
Tekken 2: A fighting game with no combo damage scaling, which is a requirement by today's standards.
Jumping Flash: The 1st 3D platformer. Although, it's a bit child-oriented, I got the game when I was about 7, so I have a soft spot for it.
Jumping Flash 2: Improves everything about the 1st game. Everything. The Navigator voice in the 1st game is the only thing better.
Fighting Force. A 3D beat-em-up. 2P co-op. The funny thing is I own this game on disc, but, put no effort into finding it, so I bought the digital version. I found the game shortly after getting the digital. It has a long play-through. I'm often ready to quit near the end of the game, because it just takes too long to get through.

I know it's not PS1, but, Rockstar is having a Grand Theft Auto Sale. Every GTA game is on sale. GTAV included. Until next Tuesday. I personally picked up GTA III, Vice City, and Vice City Stories. I'm going to get GTAIV & Episodes of liberty city before the sale ends. Everything Except GTAV is cheaper than a PS1 classic right now.

So try Alundra, C-12 Final Resistance, Gex series, Kingsley's Adventure and Legend of Dragoon  =)

Vib Ribbon is a very unique game, check it out you may like it !

Yeah, this is completely understandable.  Just because you go through the stresses of beating an insanely hard game doesn't mean you're up to do it again and again.  It's not like you're just going to power up a difficult game, and be a god at it just because you beat another game that was harder.  It takes lots of memorization, and execution to do things like that.  Sometimes, you're relying entirely around luck.

That's not something everyone wants to do everytime they play a platformer...  With that said, definitely try Megaman X4.  It's easy.  Every boss in that game is a pushover.  No exceptions.  I don't care if it's Iris, Jello-Man, Colonel, General, or Sigma.  Definitely not any of the first 8 bosses.

Plataforms... Not many of those in the PSOne, can´t remember any good one in particular.
My favorite PS1 games were Silent Hill, Resident Evil 2, Metal Gear, Legend of Legaia, Gran turismo, Parasite Eve and Final Fantasy 8. So... I can´t help you.
Hey, Castlevania Simphony of the Night have some plataforming, and it is awesome.

I forgot about Gex! That was another great 2D platformer! I didn't like the 3D sequels THAT much though.. :S
