Well... When you'r driving a car, BMW for example it has the BMW logo doesn't it?
When you'r playing MTA why not have it's name on some stuff?
Anyway why NOT have the MTA name in GTA?!
[edit]
If there wasn't a MTA Add or logo somewhere it isn't really an MTA mod is it.
And if you don't get the point to the "MTA Sigh" you will when you take it up-side you'r head.
Much like MTA this mod is just for fun.
