Dark... BlackBatman: Arkham Asylum, of which I played 9 hours, was fun. It landed at a point in my life where I had just become a new father and I started spending more time in singleplayer offline games than I did in online multiplayer games. I never beat the game, but do have fond memories of it.
Like other games I did not choose to revisit Arkham so just going to share some thoughts (see past posts tagged Batman:AA).
The first memory that jumps back to me is "dark... black". The game hit the mark for the cliche Batman "black". Everything is dark and brooding. I don't think "daylight" or "bright light" exist in the Asylum.
I also remember the combat and it was fun; albeit I do remember it being a little harder to master on keyboard/mouse than I expected. That did push me away from finishing the game (as well as having a young kiddo taking up my free time). With more time this is one I'd probably revisit to finish at some point.
