For my personal collection:
1. To play some of the games that I haven't played through yet. I am thinking about just setting a timer for 15 minutes each day and picking a random title off the shelf.
2. To get more of my systems in a "ready to play" state. I used to have a switchbox setup with 8 different consoles ready to go, but I ended up getting rid of the furniture that all of that was on, and that TV broke...
3. To sell all my extras--two big boxes full of games and controllers to sell!
4. To get boxes for my loose Genesis and SMS games because... well... it's nice to have all those guys in their little plastic homes.
For my FEMICOM collection, the two things I really, really hope to get this year are the rest of the Casio Loopy game library, Casio Loopy peripherals, and a Lady Cassette Vision. Lofty, lofty goals, but hey, you never know!
Some girly, '80s-era LCD handhelds from Japan would be nice, too.
