Nintendo World Cup Soccer - Do real soccer games regularly go 96 to nothing? Yeah, Didn't think so.
GTA III - I can usually make it halfway through the second island (Staunton, if memory serves) before dying becomes a possibility.
Sonic 3 (& Knuckles, usually) - I can get a perfect in all the Chaos Emerald levels (that's all the spheres and coins in the stage) on the first shot, and all before completing Marble Garden... Hydrocity if I'm not shortcutting my way across vast chucks of the stage, and all without breaking a sweat.
As far as I can tell, I am the only one who, with Knuckles, can complete Marble Garden with Tails assistance without glitching through walls to get there. Hell, I can barely find videos of the glitch, but none have done it my non-glitch way. At least not that I've seen.
Also, I am more likely to die from glitches (such as outrunning the game itself) than I am from any other means.
Yes, I've played them all way too much, but if you can't tell which I prefer most of all, look left.
