Minor stuff like this would add to the game for sure but it would also make it bigger. If they are planning on bringing it to the PC, I can see more details being added like this but not that many.
I remember hearing about this. I don't think it is the release date at all. Maybe it was the once planned one but then again, why would they allow store/shop people to know this earlier in advance? Most of the time they don't know themselves until they star receiving the shipments of the games.
I loved the trailer when it first came out but having watched it like 50+ times since then, it really makes me mad that they gave us VERY LITTLE on the actual story or game itself. Like come on Rockstar, why you gotta troll us?
I'd like to see more mini quests that involve traveling since it was part of the times back then. Maybe delivering packages. I honestly never minded those kinds of quests.
No need to have swimming.
The west had little to do with water other than fishing. If there is a lake or such around, it make more sense to not allow swimming to control the area without making the player feel trapped in a box. Also looks better then running into invisible walls.
