I recently bought a Game Gear game--the Japanese version of Tengen's Magical Puzzle Popils, to be exact--despite the fact that I don't yet own a Game Gear system.
Fukio Mitsuji-designed game because I hoped it would push me to (finally) pick up Sega's first handheld. (Its second being the Nomad, of course.)
Another reason I bought the copy of Magical Puzzle Popils you see in the photo to the right: Its cover art. Duh! (For a bit more information on this precious puzzler, read these previously-published blog posts.)
Don't worry, I won't hold off on reviewing this titillating title until I actually acquire a Game Gear system. I've played it enough via emulation to know it inside and out, so there's no real reason for me to wait. Anyway, keep an eye out for it if you're so inclined.
In the meantime, have any of you ever bought a game or two for a system (console or handheld) that you don't yet own?
