Lost in Random. So far the most challenging part was getting the game to run. It cannot be family-shared on Steam, it uses an online-only double DRM, and has no graphical or control options. Unless it is a masterwork in terms of storytelling and gameplay, which I strongly doubt, these flaws are critical. 1 hour in, and it has been a linear action-adventure, granted, fully voiced and well animated. In terms of story, it is a fairytale about a girl who went looking for her kidnapped sister.
Immortal: Unchained. Still in the jungle area, Veridian. Encountered an optional boss, whose arena was littered with suicide bombers who were digging themselves out of the floor (i.e. I couldn't shoot them first, but could bait them one by one, or three by three), and who could (and did) one-hit-kill me. Fortunately, I was able to loot the containers in the corners of the arena without fighting, but with a lot of running and dodging. The floor being slightly underwater (ankle-deep) did not affect the movement speed anyhow. Also, I met a single non-hostile (yet) NPC in the area. During the third meeting he was sitting in a hole, and talking to him after jumping down triggered an ambush. The NPC was just standing and doing nothing (the zombies did not attack him either), but told me afterwards that we were victorious. Probably, playing it after Lost in Random makes Immortal: Unchained significantly more enjoyable, despite the occasional unpredictable ambushes. It is also much more quiet - no overly-talkative narrator.
