What a great post/question!
I jump in and out of the forum. Mostly just been scrolling reddit, but not really enjoying it. I think, like all things, when I don't feel well I stop doing the things I like. I recognize everyone on here, but I wouldn't be surprised if anyone remembered me as I only comment so sporadically.
I've still been collecting, but taking the time to get things that are usually out of budget or rarely found in the wild. Ebay has been my friend. While I'm able to grab games I've wanted to play for a long time, I frankly don't enjoy it as much as that feeling you get when you see a cart under the glass at the shop you've been hunting for a long time. I loved dropping into the local store near where I work just to see what was new and take home a few goodies, but with working from home that's just not been possible.
Getting back out to the game stores now that I'm vaccinated is a pretty exciting prospect I'm looking forward to.
I'm sticking to a budget of "ebay" games and new releases. I've personally made the decision that after this generation I will no longer be buying new releases physically. With stuff like Xbox series your really just buying a case to go on a shelf. Half the time I don't even use the disc because the game is on Gamepass. So, my plan in the next year or so to transition to only buying vintage games for my physical collection. It's exciting to go to the game store and grab new releases, but ultimately pointless (in my opinion, and for me in my situation).
I'm trying to buy tech that makes the best use of the hardware I have as well, i.e. grabbed a MegaEverdrive Pro instead of a Sega CD and loads of expensive games. I learned that lesson after trying to maintain a Turbo CD and collection for several years.
To the OP I've been really interested in the ODE's as well. My PS1 doesn't read discs well anymore (FMVs are all jittery) and my Gamecube is iffy (the games usually run well on my Wii but might freeze on my Gamecube). I'm waiting for someone to release something that can rip vintage discs like Xbox, PS2, Wii, etc without needing a modded console. That would really push me over the edge so I could start using ODE's with rips of my actual backed-up collection. The Retro-Arch disc project is something I'm paying pretty close attention to!
