If I'm not mistaken the same "I can travel anywhere I can see" type of comment was made during Skyrim's announcement Dev playthrough.. and when the game came out it turned out that you couldn't travel to every mountaintop that you see.
Stop taking things so literal. Because if Devs had to limit everything so blatantly obvious then every open world game would have to literally be walled in at the borders because "Why can't I swim in that water? Why can't I climb over that mountain? Why can't I do anything I ever want to in any way I can imagine it?"
The dev led us to believe it's an open world. So this whole time, I was expecting an open world shooter with RPG elements - exactly as they sold it as being during E3 2013. Having played the Beta, it's instead:
- RPG lite with simple point upgrades for armor/weapons.
- Playing the same map over and over, grinding, grinding, grinding.
- The same enemies in the same spots over and over, with hit point increases.
Now, if the universe [planets] and areas within were abundant, one could possibly look past the second and third items I listed above. All that said, I'll wait for it to go on sale. I'll play Skyrim in the meantime for my action RPG fix, and Halo for my FPS fix. Both of which are superior to what seems a half attempt at both in Destiny.
