Thank you all,
I prefer to keep it simple because it is easier to provide high quality work.
On this install there are several mods, but also several plugins which are not mod dependent,
i.e., they may be use for casual/4fun. By default, all extra stuff are disabled and if you browse
the config file, you may enable what you like most for extra casual stuff.
Basically, if something is installed, is because it should a good work.
But on the beginning like 5 years ago I installed some plugins which does not looks good as this:
// With this plugin on your server, the deagle has other skin and shakes When attack. Also,
// at a headshot kill with the red thunder appears on the left of the screen and random effect
// sre apply to victim. If a player makes x headshot kills with (cvar), the lighting is dark map
// for x seconds and the hudmessage with name: Deagle Warrior appears on the left of the
// screen (cvar). Some effects with deagle, obs bug: cs can do the crash out of nowhere, one time or another.
I should remove this plugin, or fix the bug.
