Yea man I had some pretty fun times with it on GTA IV, but still I think if we get people to turn off their mini maps we can make it seem authentic. Also, the death matches seem limited in that you can't go everywhere, its concentrated to one particular area, and it's already setup. I think if its more of a role play and not a game mode it would be better.
The fun aspect of zombies was that nothing was planned out, you just moved around different areas of the map. I think that we should utilize the size and span of the GTA V map to our advantage.
There are tons of different areas and regions we can use for a zombie apocalypse setting, like up north in Blaine county or just do a cit outbreak in vinewood. Maybe even have the military role in for a stand off, or just a normal survivor RP.
We should give it a try no matter what though just to see if people like it/agree. I think that people would be open to try it.
