Here's my five:
1. Final Fantasy X
This was the first Final Fantasy I played all the way through to the end, and it left such an emotional impact on me that it still brings tears to my eyes when I think of the ending. It's been at least five years since I finished it.
2. Metal Gear Solid 3
Again, the first in the franchise that I completed, and every single aspect has something I find engaging. The sneaking and camouflage system is surprisingly robust, and way ahead of its time. The story and characters are engaging, with a few twists to keep things interesting. Because of the time period, the story has aged very well. It also marks the second game to ever make me shed tears during the end sequences.
3. Kingdom Hearts
I honestly cannot pick a single entry of this series to feature on my list, so I will be referring to the most important in the series, namely 1 and 2, and Birth by Sleep. Simply put, I love Kingdom Hearts. Everything from the endearing story, to the incredibly entertaining combat, not to mention the sheer level of variety, makes this series a collection of modern classics. Birth by Sleep in particular is an amazing experience.
4. Red Dead Redemption
I was honestly surprised by how much I loved this game. I never expected to grow as fond as I did of John Marston. To this day, it's still my favourite sandbox, and the ending is one of my favourite and most satisfying moments in gaming, ever. Aside from that, the mechanics are solid and enjoyable, aside from the multitude of glitches.
I know OP asked for five, but I can't think of a fifth that measures up to these magnum opuses.
