Okay, so here's my tips/attitudes to deal with hoarding porn games:
- Burn it all down. Sometimes it's nice to just delete everything and start from zero. You'll end up building up a huge backlog again in short order, but for a few weeks it'll be nice to play games, delete them when you're finished, and always have spare room.
- Don't even look at unfinished games. I get it: there are some really good looking games on v0.65. But you'll play it, be slightly unsatisfied since there isn't a conclusion (or put up with some jank since it's still in development), then end up playing 1-2 times more. Instead you can devote your time to only completed games. They can have a more satisfactory ending (since they actually have an ending), or you can happily dump it when you realize the poorly-implemented combat isn't just a placeholder.
- Prioritize big (as in GB) games first. There isn't usually a correlation between archive size and playtime, so getting through 1-2 large games can easily clear up 5 GB.
- Buy it. No need to keep a game on your pc when you can always just download a new copy from Steam/DLsite when you get the urge to replay it.
- Only keep the savefile/translation patch. Whether it's a game you want to revisit or something that's still in development, hanging on to just the save file will help conserve space. For Japanese games I bought on DLsite I'll just hang on to the translation patch since they're easy to install these days and take up far less room.
- Abandon games sooner. If you've paid for a game you tend to give it more of a chance, but these days I'll dip out if specific-to-me annoyances are present early on. Maybe the game gets better, maybe it doesn't, but in any case there are dozens of games waiting in the wings with potential to be good from the very beginning.
- Prioritize keeping older or niche games over popular ones. It can be harder to find working links for older or niche games, while popular games tend to still get updated links even when they stop being new.
- Better organization. Some people like bookmarks or watching threads, other have a document or Excel file with information about promising-looking games. I tend to make individual text documents for games I want to remember with some useful information inside (themes, completion status, translation status, if bugfixes are incoming, etc). This is makes more sense with Japanese games since they all have a product code, but there's also Western stuff I've forgotten about until randomly browsing my h-games folder. It's possible I won't be able to find links once I finally get around to wanting to play those games, but in that case I can just wishlist it and wait for a sale (or just play other games; there's always more games).
The same system largely holds true with animations, though I can also save space by converting them to x265.
