I would go with Prince of Persia next just to get it out of the way. It hasn't aged very well and it is just kind of OK, in my opinion. Combat is essentially the same combo over and over again until you can kill whatever you're fighting (with some enemies taking an annoying amount of time to die), the audio when the characters are talking can be very quiet at times, the story is lackluster, the Prince is unlikable, and it is a very short game. I will say that some of the puzzles and platforming aren't too bad, though, if my memory serves me right.
Metal Gear Solid 3 is not for everyone. I personally love story driven games, and I really liked the story in this one. Gameplay will consist of a lot of patience, especially if you play on anything other than easy. Camouflage and stealth are the name of the game, and if you want to make at least one 'boss fight' less annoying later in the game you'll want to be as stealthy as possible to avoid killing people. If you do go in for combat generally try to choke them from behind for less hassle. Shooting people works too, if that's the way you want to go. Both systems work fine. All boss fights are unique and epic in their own way (The End, anyone? That fight still blows my mind, especially the 'alternate' ways of dealing with it. So unique.). Story wise, the game can be described as...poetic (think anime). Cutscenes are long and overdramatic (and just downright silly sometimes), but the overall narrative is actually quite serious. And honestly, some parts of the game I see as downright beautiful in their presentation (last boss fight, for one). This game is much longer than Prince of Persia and I feel it should be given more time to appreciate it, so this should be the last one to play. If you don't have a taste for the melodramatic, though, you will probably not enjoy this game very much.
