My #1 game doesn't exist anymore, as it is Classic, BC, WOTLK World of Warcraft. And even if it was revived, the community back then is much different compared to today that it still wouldn't exist. Will be hard to find a game to top that.

StarCraft: Brood War used to be my #1 game but it got replaced and strangely not by a new game surpassing it. My "new" #1 is Chrono Trigger which is actually older than SC and which I played before SC too. 

I made the change when I started including how likely I'd be to replay the game and since much of the fun I had with StarCraft was linked to me playing Terran vs Protoss against my brother when we were both living at my parent's house, I figured it couldn't really stay #1.

Chrono Trigger on the other hand, I could play anytime and still love every second of it!

So far it hasn't - And probably will not. I can only beat a game 5 + times so and so often... your reign shall remain supreme Ocarina.

depends on how often it comes along. so far, its been about once every generatin

GoW2 on PS2
Red Dead Redemption on PS3
and that lasted until The Witcher 3 on PS4

My number one(s) never change. My number one 2D game is SMB1 and my number one 3D game is OOT. Neither have been surpassed as far as the impact they had on me. I haven't been awed like that since and probably never will be again.

It's been 10 years since The World Ends with You release. I don't think there is a game I would have called my number one game before that.

Not for a long time. It used to, back in the '90s gamechanger after gamechanger came out, but then Ocarina of Time released. And so it's been the #1 since 1998. Nothing has beaten it, it was the ultimate gamechanger, and since even a Breath of the Wild isn't going to, I doubt it'll ever lose that top spot. Only once did something come close, in 2003 with Knights of the Old Republic, but even then it was pretty clear which game remained #1 and which would become my new #2.
