I would also like to add x-com on Ironman. Losing a soldier because you got sloppy and arrogant; putting them in an indefensible position and watching them get slaughtered. Do that enough times and you literally cannot win with just rookie replacements. But yea, I felt actually bad for losing some soldiers in my Ironman runs.

XCOM no doubt. I once lost a veteran ranger and I was bummed for days. He was mind-controlled by the enemy and a panicked friendly shot him. Tragic.

Also Darkest Dungeon. But problem with DD is that though you may lose characters permanently, it is impossible to lose the game, as both time and number of new recruits are essentially infinite. Atleast in Xcom there is someway to lose the metagame, if enough countries withdraw support(I think), but in DD, it continues as infinitum.

XCOM has too much of an RNG factor for me. You can make the right choices (gearing, squad composition, positioning, targeting, etc.) and still lose soldiers due to streaks of misfortune. I personally hate being punished (usually brutally) due to factors outside my control, so I eventually gave up on the game.
