@2UP: Hahahahaha

@Topic: You'll most likely hear repeats of the same games, but I'll recommend you a few games you can pick up (beware some links may have spoilers in them, but I tried to give you mostly intro stuff)

Crash Bandicoot is a 3D platforming game. It's not free-roam like Mario 64 or Banjo Kazooie, it's more like an overhead style. The basic idea was to turn classic sonic into 3D and it worked really well. Worlds are very well designed and the game has good amounts of challenge. Crash 1 is hard to complete if you want 100% and Crash 3 is on the easier side (however some additional challenges make it challenging too). I've never played Crash 2, but it's Naughty Dog, you can't go wrong
Crash Bandicoot 1 - Level 1Spyro games are more like Banjo Kazooie, a 3D, free-roaming collectathon. You are a young Dragon who has to go through several worlds and collect items or rescue dragons. It is more like a Mario 64 world, where everything is joined through portals, unlike Crash which is more streamlined. The worlds are expansive, the games are not very challenging, but they were fun nevertheless.
Spyro 1Someone already mentioned Metal Gear Solid, it's a 3D cinematic stealth game. It is a game about a spy called Solid Snake, in which you must infiltrate the base and find a weapon of mass destruction called Metal Gear. I have not played it myself, but from what I hear it's very good and challenging.
MGS1Final Fantasy 7, most popular, and most hated among fans because of that popularity. I really enjoyed the game, the graphics might be a bit outdated (especially the characters), but the story, the battle mechanics and the music are still as great as they were 10 years ago.
Same goes for
FF8. It has different battle mechanics to FF7 and people tend to bash the game because of it, but I really enjoyed it. It shows how Square could pull a twist on their own formula.
FF9 I've not heared about as much, but it's more like a throwback to the older games (FF1, 4, 6) except turned into 3D! From what I hear it's very underrated so I'd recommend to check it out.
Crash Bash. Yeah, call it a Mario Party clone or whateveer you want, that is not the case. This is a party stylised Crash game in which you have to play a series of levels, which are minigames, to move onto a boss and go to the next world. Best thing is, it has a story mode which you can play co-operatively. And the different games are varied and repeats of the games have some twists on the formula. Bare in mind though, AI is AI and sometimes you will cry. Especially on the bonus challenges.
Crash BashTomb Raider 1-5. (Just so you know, they're all pretty similar and I hear that 2 was the best.) Tomb Raider is a 3D platform adventure series about Lara Croft, who goes to different places to find treasure. I won't go over the story as it's not the main focus, but the game is challenging experience, filled with secrets, puzzles, platforming and fun. There is also shooting, but it's no CoD. But it's no TR 2013 either.
Tomb Raider 1A game that rarely get's mentioned:
Pac Man world. It's another 3D platformer, with no free-roaming camera. You are in role of Pac-Man, who, on his 20th birthday, has to travel through several worlds, challenge bosses and ultimately, rescue his family. The game has varied bosses, very cool worlds and is challenging... Or you can play the classic more which is just Pac-Man.
Pac-Man WorldI don't have itme to list all the games but other honorable mentions are:
Klonoa (a 2.5D platformer, but it's very rare and expensive),
Suikoden games (JRPG series, another rare gem),
Jackie Chan Stuntmaster (a 3D beat them up with elements of platforming and secrets),
MediEvil (a 3D adventure series, kind of like zelda with exploration of levels and puzzles, a solid recommend, check it out),
Parasite Eve (underrated Square RPG, with elements of action, it is very different from Final Fantasy games as it takes place in real world and has more dark tones, a solid recommend),
Disney's Tarzan (Think of it as DKC of Sony, it is a 2.5D platformer with tons of secrets, the game's decently chalenging) and
]Crash Team Racing (a mix of Mario Kart ghameplay, with Diddy Kong Racing styled missions, with Crash characters and worlds). I'm probably forgetting about some games, but these are just a few. I'd especially recommend
Final Fantasy 7/8/9, MediEvil, Parasite Eve, Pac Man World, Crash Bandicoot 1/2/3, Crash Bash. Hope that helped you
