Exactly the same as now minus the amount of players, events, physics, content released.
It also was much glitchyer and the addon system was really... well whatever the opposite of "idiot proof" is.
I had over 7 varieties of the Barreta Sniper Rifle at one time.
Haha, yeah...
There was a billion add-ons in v7-v8 and half of them were half baked and buggy.
Besides that once you downloaded an Add-on, then you put the shapes, textures, scripts etc. in their own folders... You could almost never find them again. I remember when i was trying to figure out that add-on system on my own, after replacing the shapes folder twice or so. Yeah.
Also adding onto badspot's post, we actually did have Space Guy's Events. Even though they didn't work as well, they worked well enough to make homing turrets and stuff. Probably besides that, the one mod I always loved was old TDM. That plus the old GSF - San Andreas.
Anyways, so what I would do is make 3 teams on my 32 player server: Black Gang, Blue Gang, and the Red Gang. What would happen is you would run about the city looking for weapons and vehicles to kill the other gangs. So it was a huge drawn out TDM. And just for 'the fun' I allowed people to build gang flags and gang signatures on buildings and what not. Yeah, that was fun. That was way back too, back when my name was still Snip3r. Ah well, enough of the memories.
