scared? right offhand only 1 comes to mind but i already went over why in another thread, minecraft's last map area
other than that i don't even remember, i do however remember a few that came off more as creepy or just disturbing though.
FEAR 1 & 2: first game was increasingly creepy as you go through it but that was likely the main idea, for the 2nd game i found the parts around the ending kinda disturbing because of what was happening (not going into details there).
um... i gues the most recent game was that short series based on luna from mlp:fim. Luna Game, sadly after playing through all 5 games it left me wondering how mentally the disturbed the creator was when making the games more than anything. i'd say mildly creepy but thats about it. i've seen better and i've seen worse fails
oh and there was also the game Slender which i didn't play but rather watched a few LP videos of, the videos were enough for me. i don't see myself ever playing that game honestly, i might try amnesia except its a massive download which i can't get done easily at all so more than likely LP video's on that too.
