Pokemon Sun was a game I recently completed, in only 4 days as well. Good god, the ending made me tear up a little. It's probably just me, but Pokemon games are becoming more and more emotional in terms of story, and I like that. Now I'm trying to complete the Pokedex (5 to go) and shiny hunt (unintentionally hatched a shiny Spheal the other day, my god is it cute).
On a less exciting note, I also completed Cold Case Investigations. Played it because it was made by some of the same people who made Hotel Dusk (whose creator company went bankrupt 5 years ago), and was really excited to play it. Was fun, albeit short, but the ending was...unfulfilling, very much so. Apparently it's intentional, as it's episodic, but as I actually haven't seen proof of that statement I am unsure what to think.
