I totally loved the glitchiness of old video games. Back in the late 90s I recall spending hours and hours playing Tony Hawk Pro Skater on the N64 and rinsing the glitch on the Chicago Windy City level trying to accumulate the highest score possible.
My friend Nav and I would take it in turns trying to hit the rafters and watching you skater get up unfeasibly high usually at a totally weird angle. One of the best memories from my uni years.
Sadly programmers are getting better and there are fewer and fewer of these little gems in modern video games.
Bring back the glitch!
