@Snake, I suggest you to keep a define in the gangzone sections for now, just like disabling it, but still it's coded:
#if defined INCLUDE_GZONES
//Gang Zone stuffs.
//bla
//bla
#endif
So that whenever you feel to enable, you can just define the "INCLUDE_GZONES" above the script.
@Matthias, I've just told that there will be 30 gangzones only. We can increase it if we want so, GTA SA anyways got small areas too, that kinda zones won't be added. We can create our own locality for setting it as gangzones.
@Jono, No not just in LS. It will be around the main locations : LS, Red County, San Fierro and Las Ventures.
