LTK, noradar, Pistols. That's how we played it on the N64.
Automatic Weapons and Shotguns take a lot of the fun out of LTK.
It wasn't that bad on the N64, coz your aiming was far less accurate then in GES.
If you wanna have the true GE64 experience, grab some friends (i suggest 3), do a password protected server, disable jumping, maybe play just classic maps and use some N64 Controllers.
