I'm not really angry at anything, seeing as the game isn't out in the US yet. The only thing that really annoys me is how stupid the fans are. They pretty much wanted a G/S/C remake to the point that they use ambiguous 'clues' to hold out hope for one, but when it is revealed and people learn more about the content, they complain about the most minor of updates, the most retarded being the complaints about the grass being changed (which I would be much obliged if someone linked me to such a post, seeing as I haven't personally seen one) seeing as it proves how unnecessarily cynical a lot of the fans are (that doesn't make any of the other complaints anymore deserved, since people should stop whining about Pokemon following them and deal with it) even before the game is released and that anyone that has complained about that is a moron without justification.
tl;dr I hate how a lot of people complained so much about a game they wanted and then many of those same people went as far as to bitch about subtle aesthetic details when info is released.
But if I had to say what confused me, I'd would have to say the unchanged rosters of gym leaders (why would Bugsy have cocoon Pokemon) but the rematches somewhat make up for that, how it's unnecessarily complicated to rematch Gym Leaders (or anyone in general) because you have to get their number on a certain date, call them on a different date, and then rematch them, and the Hoenn/Sinnoh Sounds, which seem to be more annoying and less practical than the PokeDar.
Other than that, I think that HG/SS will be a pretty good game once I get it.
