Legend of Valkyrie, Japanese version on Namco Museum 5 (a very recent purchase off Ebay), reminds me I still need to play my copy of Xandra no Daibouken (Whirlo to you UK chaps), first game in the Valkyrie series chronologically. Then there's the middle game, which came first, Valkyrie no Bouken, which has an absolutely superb remake for the PS1 via Namco Anthology 2, and I must have it! It was also on the 3DS as well, but digital and Japan only, and only as a bonus for some Project X game, or something to do with Capcom and Namco for the machine. I'd rather a physical copy, so PS1 it is (the 3DS version added a second playable girl, why, I dunno, should been Sandra, the green guy).
