Nier: Replicant ver 1.22... (Xbox One)
Never played anything in the series and this one absolutely convinced me to try out more. Gets a bit repetitive but the additional story bits given through NG+ cycles made it worth it (to me). But it's probably not everybody's cup of tea, because of the mix of classic JRPG tropes with some pretty crazy stuff you won't find anywhere else (except for maybe Automata).
Limbo & Inside (PC)
I still remember the hype over Limbo when it came out but I didn't feel like it really lived up to it. Apart from the style and the atmosphere, I didn't find it particularly memorable.
Inside on the other hand was pretty good. Not perfect, but it ironed out many mistakes that happend in Limbo such as story, controls and most puzzles.
