I have really cut back over the last few years too, due to both space and financial reasons. I was laid off last summer and sold a ton of Black Series and Marvel Legends on Mercari to get by. It really does create a snowball effect because now I want to get rid of 90% of what I own and condense everything down to 2 bookshelves or so. I've had a ton of internal dilemmas about Star Wars, mainly which figures to keep, and whether or not to keep alternate costumes (i.e. Yavin Luke and Stormtrooper Luke as opposed to just having Farmboy Luke, Bespin Han vs ANH Han, etc.).
Hasbro Star Wars: I made the mistake of hopping over to 6 inch from 3.75 inch, but I haven't bought anything since 2021, maybe early 2022, and it will likely continue that way. I'm trying to downsize like crazy so I'm planning on getting rid of most background characters and army builders. I also have my entire TVC/3.75 inch collection at my parents' house that I need to go through and sell. I want to get rid of everything outside of a few vehicles, and maybe the main OT crew to put inside the BMF.
Hasbro Marvel Legends: I managed to sell all of my duplicates outside of a few Spider-Man figures, but I'm still interested in any Spider-Man characters, and to a lesser extent, X-Men. Most of my main display X-Men figures are Japanese imports, with ML filling the gaps. Interested in a few of the X-Men '97 figures, and I'll buy anything based on the Raimi movies and 90s Spidey animated series. I'm debating going back and getting Andrew Garfield Spidey and the Final Swing Spidey but for now I'm happy with just Tobey Spidey.
Bandai SH Figuarts: These are my "main display" figures. I have the TPM 25th anniversary Qui Gon and Maul on preorder, and will continue to buy the 1-2 Star Wars offerings they put out each year. Last year I only got the Obi-Wan and Vader based on the Kenobi final duel. Both great figures! I do want to get rid of some stuff that is inferior to the Hasbro figures, such as Count Dooku, but I have almost every figure made from this line and my OCD hates that idea!
MAFEX: I really only buy their Marvel comic book figures, and only go after Spider-Man and X-Men figures. I didn't get to buy the Scarlet Spider that came out in 2023 because of my layoff, but with the Hasbro ML version on preorder, do I really need it now? Time will tell! There are a few cool Star Wars offerings coming, all based on Mandalorian S3, but do I really need to pay $100+ for a slightly better Bo Katan? Another Mandalorian? I think I counted the other day that I have 8 across 3 lines, so unless reviews come out saying those are the best figures ever, I'm skipping them.
Hasbro Indiana Jones: I never got into this line because I went all in on the 2008 line. I did pick up the SHF Indiana Jones, and I'm hoping that the Adventure Series hits Ollie's or Ross because I want to track down a Marion, Short Round, and Henry Sr. for cheap.
McFarlane DC: I own a ton of the DC Collectibles Batman TAS line from 2015-2020, and Todd has been rereleasing some stuff exclusively at Target. I picked up the Scarecrow rerelease a few weeks ago because I missed the original version of that one. There's an Alfred exclusive coming at some point, which is nice because that was originally only available in a Haslab priced Batcave set. After that, I just need to hope Todd rereleases some of the figures I don't have!
