Let me tell you ser, The whole map is the same, all the roads all the turns all the parking, etc. The only changes that eflc has are some buildings like, I mentioned before, bahama mamas, maisonette 9, hercules etc. Only these few buildings are different rest all are the same. EFLC still uses GTA IV as its base.
eh now I get the idea, we are trying to let both IV and EFLC players join a server which uses IV map with all T4 features, rest of the EFLC content gets removed, alright.
I am sorry I'm against it, why. Because there is much more content that I would rather enjoy instead of an extra 2-3 players. I don't feel making people with IV only able to join is going to help increase player count, I would rather get more content/advertise the current server. T3 is a bad idea too, I just realized that.
Here is a post on "GTAForums" which contains the map changes, and a mod to apply EFLC's map into normal GTA IV. I am not trying to advertise anything but just in case anyone wants more knowledge.
HERE.
