See attached and tell me that you can seriously tell which ammunition is selected in the EE version (bottom pic).
Yeah, I see what you mean here. I don't have totally terrible vision, but it's not as clearly shown the arrows are selected in the EE. The shading behind the selected item is subtle and no longer has a highlighted border, making it harder to tell what's selected at first blush. For someone who is colorblind, this will be a hindrance depending on the severity of the condition. Had I been designing this, I would have left the subtle background change, but also added a border highlight in the same color as the font.
As a person who is colourblind with reds greens and browns, I can tell you that it is a hindrance. Looking at Hickory's screenshot was bad enough, playing the game like that would be annoying. Incidentally, I have the same trouble in IWD1 where thief skills are shown active by a poxy red border that I can barely see. I usually end up turning the abilities on and off and checking the message window to make sure they are still active. In the case with the selected ammunition in BGEE, I would have ended up picking up the ammo I wanted to use and put it back in the quiver to make sure that is the ammo I would be using but why should I do that when in the original game, the bright border highlighting the selected ammo is clear and saves a colourblind person like myself from messing around like that. What isn't broken shouldn't be fixed, the selection border should have been left in.
Playing though Neverwinter Nights on the other hand was so aggravating it almost made me a follower of Ilmater!!!! Two areas in the hordes of the underdark had puzzles where you had to select colours in the right sequence. In the first area, I couldn't tell the difference between the yellow and light green. Because of that, I also couldn't tell when the colours changed and cos of that, I kept messing up the combination. I was able to get past the puzzle with some serious save scumming though. The second was even worse. It was the area where you had to teleport over a bunch of islands in a lava pit and you had to flip 3 levers to make the 3 statues radiate the same colour except I couldn't tell the difference between two of the colours and I was stuck in that area for a few hours!!!! First, the puzzle was a stupid idea as it was, second, not being able to tell which statue was radiating what colour made it worse, third, if I had the wrong combination (and I did a LOT!!) I needed to back track and flip levers AGAIN and fourth, because you could only teleport to certain islands at the right time, it made backtracking tedious AND time consuming.
Either the devs don't consider these things, they had their brains turned to liquid shit by mind flayers or they are followers of Loviatar. Whatever the reason, I wish they would stop it already.
