I'm rather late for this topic, but I didn't play anything related to the season, but unconsciously I got into a Resident Evil kick by late September buying a few games in the series that I ended up getting this month. I also bought The Thing for PS2 on September 10th, and after a bunch of delays and mishandling by USPS, I ended up receiving the game on October 1st, which I found drolly. Additionally, I’ve been trying to find a cheap copy of Baroque for PS2 for quite a while and curiously ended up finding and getting it at a good price this month.
If I were to make any recommendation for the sake of staying on topic, but maybe for next year, I guess I would recommend
The Thing and
Ghosthunter, as well as
Michigan: Report from Hell if imports are of no concern. Parasite Eve is also a good choice (even though the game occurs during December).
Also, Ghostbusters: The Video Game. I guess that one goes without saying, so maybe that's why nobody mentioned it.
I'm thinking of playing Scooby-Doo Mystery for the Super Nintendo this month.
Maybe give Scooby-Doo! Night of 100 Frights a try. While I remember watching the show as a kid, I've never considered myself a fan of Scooby-Doo (although I loved “A Pup Named Scooby-Dog” growing up), but I’ve always been curious to try this game for quite a while now; I’ve had the chance of getting it, but never do.
