As for glitching, I have friends who are glitchers, and sorry to say this, but I agree with Serio.... doing the same thing over and over and over again for hours, just to break the games rules seems whack to me. Why do that, when I can simply reprogram it to do what I want it to?
Well, as long as your statement doesn't stereo-type what real glitchers do, it's fine. It ain't like it's "senseless" repetition.
I'd accept more from someone who really glitched the game and quit, but I find it hard to accept an opinion from someone (in general) who didn't even try and just assumed the whole point of glitching.
In response to the topic, there are nice challenges that are possible with just you, your SOTN and your PS (or PS2 or emu, whatever).
1. 0-kill challenge
2. 1-kill challenge
3. 425% map challenge
4. 24% only map challenge
5. Low-map/All relics chalnge (55% map)
And lots more. Of course I'm not advertising it for people to do it, just plan info for all that they're all results of nice and fun work over the years.
