Got into the original Dark Forces. The plot is a more generic "elite commando taking missions from his organization" story rather than Kyle going on a quest for highly personal reasons as in the next installments, but it's a cool story nonetheless. The series gained more character later on.
I suffered through two whole missions with the archaic control scheme and gave up on the third. Then I found the GOG version comes with a program to rearrange controls, set up a traditional WASD scheme and now I can move like a breeze. I'm already addicted. The third level is not very difficult on hindsight but kept my adrenaline high all the time.
Despite potato graphics the second level has some pretty landscapes. Flowing water, ruined buildings and a dark purple sky with mountains and large round stars. On the other hand the fourth is very barren. It's set in Fest which I know from lore is an ice world but that is barely noticeable except for everything being white and some windy sound effects.
