As of February 8, 2015, what are your favourite games of all time?

[Zekkyou]

1. Final Fantasy IX
2. Ratchet & Clank: Up Your Arsenal
3. The Last of Us
4. Steins;Gate
5. Portal 2

I could spend hours explaining why i love each of these titles, but the one thing that unites them is that each (relative to their time and genres) made me appreciate how much potential gaming as a whole has.
