I played the first 4 missions of Destiny last night and enjoyed them, even though they were exactly like the beta, as far as I could tell. I got the slight impression that thing were a little harder than the beta, but that may just have been my lack of practice. But I did notice some glitching that wasn’t in the beta: Some enemies were glitching between a couple of different spots, much like laggy play in other multiplayer shooters. Except these were computer controlled enemies, not players, so it wasn’t due to someone’s crappy internet connection. These were also very low level enemies (level 2), so it wasn’t some special ability – it was a glitch. It wasn’t a terrible problem, but it sure messed up my aim as I tried to kill them. It also messed them up, too, so at least the disadvantage went both ways.
Other than that glitch, all seemed just as good as the beta, and it was good fun. I played the 4th mission with a friend (who was much better than I am), so that was great fun.
One of the things I like about Destiny is that the enemies are not omniscient. They can be surprised if you sneak up on them, and some of them can even be a little cowardly if you knock down their shields. Overall, the feel of the game is great, so I’m looking forward to playing more.
