Have you ever beat an entire game in a single sitting/day?

The only game I've ever done this with was Heavy Rain. I played the whole thing on launch day in one 13 hour sitting, which was... probably at the top of the list for geekiest things I've ever done. >.>

Um, I can only remember beating Mega Man 10 in a single setting right on the release date.

I still never saw the ungodly tall Wily Tower coming.

Yes, mainly FPSs.

Let's see...

Mirrors Edge, I think Portal... probably others, can't think of em.

Depends on the game.

Super Smash Brothers Brawl? Yes. Metal Slug Anthology? Yes. Scott Pilgrim Vs. The World? YES. Castle Crashers? HELL YES.

But Tales Of Symphonia, Persona 4, Borderlands? Oh god no.

All the time. Depends on the type of game. Short ones like Mega Man are designed for you to do this.

Ocarina Of Time.

I've beaten Portal in roughly one day, and VVVVVV in one night, even the trinkets.

Yes. Mainly shorter games like Dragon Quest 1 during longer car rides.

Oh, and just to make sure it's said: both of the games I listed, while short, are really fun. Highly recommended.

I just did this today with Sam and Max Hit the Road (granted I was using a guide)

And most Shooters I have also done this with.

Super Mario Bros. Super Mario Land. Depending on how you count Warp Zones, also Super Mario Bros 2, 3, and World.

Mega Man 2. Mega Man 3. Mega Man X. Didn't play MM 1 or 4-8 until the Anniversary Collection, which had a save feature.

Sonic the Hedgehog 2. Sonic & Knuckles.

Street Fighter II (not any of the fancy versions, just the plain SNES release; not as Dhalsim).

Pokemon Silver, on a 1300% speed emulator

Panzer Dragoon Orta. I was surprised that I did it to.

Megaman 2-7. All of them in one day. I only needed to use the save feature in the collection for 1 due to it being the hardest (for me). As well as, Megaman X 1-3, though on different days.

Super Mario RPG, the original Legend Of Zelda, the Contra series (except for Contra Hard Corps), Gunstar Heroes, the second Rocket Knight Adventures game, and Cave Story (the normal ending; it took me a several days before I managed to earn the true ending).

My brother and I finished Super Mario Bros 3 in one night. No warps. Good times.

My cousin and I almost beat Mortal Kombat Shaolin Monks in a single day. We made it to Shao Kahn before losing one too many times.

Ocarina Of Time

Darn, it normally takes me about a week, but then again I like to do sidequests.

I usually take my sweet time when playing games, but I have beat the first three Sonic games within a few hours.

A few arcade fighting games? Do those count?

If we include indie stuff, I do this all the time. If we don't, then I don't think I ever have, mainly because I rarely buy short games

Wait, do you just mean first run? Because if not then it's too many to count.

Pokémon Snap was the first game I beat the day I got it.

I've been all kinds of games in a single sitting, though. I do it with Super Mario Kart (and Super Mario Kart:Pro Edition) and Pilotwings kinda regularly these days. It's like a mental warmup.

Yeah, Deus Ex and Metal Gear Solid 2.

Zone Of The Enders and the second one.

Probably quite a few, but Chameleon Twist (N64) and Felix the Cat (NES) jump to mind, both great rentals. Agreed that only first plays count, since I'm sure all of us speedran old favorites.
