I'll get started with the games that fell off my list this year. There are five new games on my list this year, so that means five others had to be dropped. Won't spend too much time on these.

• Batman: Arkham City (PS3, 2011)
  
  • The best game in the Arkham series, and one of my favourite open world games ever. Part of the reason for Arkham City falling off might be simply because it has been such a long time since I've played it and I've just forgotten too much of the experience. Still, as of today, it's off the top 50.
• Portal 2 (PC, 2011)
  • Probably the best puzzle game I've played, and one with excellently written characters and surprisingly engaging story when the details start opening up. 
• Super Smash Bros. Ultimate (Switch, 2018)
  • I've noticed that in recent years I've fallen off fighting games quite drastically. In years past series like Smash Bros, Tekken, and Soul Calibur were among my favourites, but with SSBU now falling off there are no fighting games left in my top 50 anymore. Maybe I'll get the urge to get back into them one day, but for now they're all gone.
• Super Metroid (SNES, 1994)
  • One of the SNES' best, just not quite good enough to remain in my top 50. Mainly just a victim of shuffling around my list, and obviously the five new games that made it in this year. 
• Command & Conquer (PC, 1995, 2020)
  
  • A game I have so many fond memories off from back in the day. It was effectively my introduction to the RTS genre, and I can still go back and play it today, especially with the remastered version having been released a few years back. It hasn't necessarily aged the most gracefully in some areas (AI), but the power of nostalgia can forgive a lot, and there's still a lot that is genuinely excellent about it. 

Alright, might as well get the first hints out of the way here too.

#50: Geohound

#49: A knife is a key to open a path to a city hiding a big rock

#48: So many rodents

#47: Angry dad tries to be not quite so angry

#46: 108 part 2

The above picture is not my base by the way, something I found on the internet. For my base I love vast network of tunnels connecting different above surface structures.

Super cool way of doing clues, I like it! I'm gonna avoid spoilers each time and see if I can work it out myself - in this case I couldn't.

I will try to hint one at a time going forward.

Sonic the Hedgehog... er, the first one? Genesis version?

#49: A knife is a key to open a path to a city hiding a big rock

#47: Angry dad tries to be not quite so angry

#49: Wake up with a hell of a hangover.

Yes... And yeah I mean "archaic" in the context of video games, so just an old game, not like some sport the Ancient Egyptians played or something lol.
