How would you feel if (this is highly unlikely btw) Rockstar only gave us very minimal information on GTA V right up until release? Let's say they gave us the basic plot, a few main character details and hardly anything about the Los Santos map itself.
When GTA III came out I hadn't even seen or read anything about it so the whole game and map was an unknown thing to me. Every corner I turned and every mission I was given I went into blind, everything was new and fresh. So, how would you feel if GTA V were to release with hardly any information, would you prefer it that way or do you want as much info as you can get before release?
