I thought it took part in the convo last time this thread popped up, but I guess I didn't.
I'll give a tl;dr at the end. In my youth, the extent of my PC game playing was limited to C64 games, and then I immediately jumped to Atari 2600/SNES (Early 90s, yeah, pretty late for Atari) and went from console to console. In high school I was introduced to UT2k4 and Onslaught mode. This was my first experience with real PC gaming (C64 was little stuff, like all ASCII art and shit, probably not even commercial games). I really really liked the vehicle combat. This was almost exclusively the UT2k4 demo so you really only had access to the Hellbender, Scorpion, and Manta. I really can't recall if the Goliath and Leviathan were in the demo. (ONS-Torlan) My favorite thing to do was drive around and mow people down. At this point I had no handle what so ever. So early on, I went through some different names like "Doom", "Ima Kilyu", "Meaculpa", "Desperado", and "Get Quashed". Eventually I wanted "Vehicular Manslaughter Man", but obviously that was too long so I just went with "Ignition" and occasionally used "Damage" for games that wouldn't allow 8 characters. "Doom" and "Link" for when it was even fewer characters. Most folks assume the 365 is because the standard name was already taken, but actually it's from the same scenario. My friends and I had a gaming clan called Clan 365. I think our idea was that we'd whoop your ass any day, but not on leap year, that's a day of peace.
tl;dr "Vehicular Manslaughter Man" was too long.
