I wish the custom of doing this had never caught on. I can still remember the number of complaints that swarmed the feedback for Morrowind when it came out. People complaining in tidal waves that they had no idea what to do or where to go for the very first quest in the game...despite one of the first characters you speak to telling the player where to go and who to talk to, and a character you meet moments later giving the player step-by-step directions on exactly how to get there.
Give it 5 more years to until Oblivion's release...and every game under the sun included a constantly displayed mini-map with dotted line showing you where to go, a compass somewhere on the main screen with huge quest marker icons, a glowing path to follow in-game, and a huge
! icon over the entrance to whatever "secret" entrance your character was supposedly "trying to find".
I get that sometimes games can be a little unclear, or there might be a gap in the info a character is given, so having a
way of activating something like these neon breadcrumb trails to follow is useful, but I'd still rather have it on-demand.
I think a button we tap to activate a temporary overlay that highlights points of interest or makes the icons appear for a few seconds then fade away would make games much more immersive. If a player wants the help, it's there. If not, we just never tap the button.
