Thank you so much for responding! I totally understand, I'm a but if a project junkie myself, so I respect the grind, and I also respect taking breaks and pacing yourself. You should only jump in if it's going to bring you joy!
But if you do ever cover Game Gear, Wonderswan and Neo Geo Pocket in one last Handheld Encyclopedia volume, even years from now, I'll be looking forward to it. Or anything else you do!
Oh, and yes! All printed out in Hardcover form. Don't worry, I kept the volumes split into separate books haha. Can you imagine the binding on the PS2 series? Those are actually the last of your works that I still have to print. Here's a picture of how they look on my shelf! (I'm sure you can tell which are yours)
