I was surprised to learn that a remaster of Flashback is available on Steam.
When I was young, it was one of the games I enjoyed playing.
I recently picked it up during a -60% sale (for € 3.99), and I'm (re)playing it now.
Lately, every now and then, I have been playing Super Mario 64.
I found out I’m going to have to collect 70 stars to fight Bowser in the end, so it’s going to be tough.
I have played the Commander Keen games that are available on Steam after more than 10, perhaps 15 years or so since I last played them; I have faint memories of playing them in the late 90s-early 00s.
I have finished the first one, and I'm almost done with the second.
As a kid, I couldn't finish 3 & 4, but thanks to the Internet, now I know how to do so.
Also, still playing SNES PoP, Zelda: A Link To The Past, Super Metroid and some curious NES mods for Mega Man and the first Ninja Gaiden of all things. The mod of the latter is titled "Deadpool" (yes, the Marvel character) and it's a mostly complete overhaul. Really cool, and it inspires me to be able to do such type of overhaul to PoP, or Ninja Gaiden. I also beat the third Ninja Gaiden in its japanese version.
