If you’re interested in checking out some of the lesser-known gems on PS2, consider giving Dark Cloud and Dark Cloud 2 a try. They’re both completely standalone, so you could skip the first and try the more beloved sequel. The hook for both is that as you explore dungeons, you get blueprints and resources to rebuild the outside world. Honestly? I don’t know if they aged well, but I had a blast when I discovered them about 20 years ago.
Ooh, I wanted to play DotAGE after enjoying the demo when it came out, but I held out on the hopes that it’d come out on GOG (and eventually forgot)! Thanks for drawing attention to it - I’m picking it up now.
