an open-world skateboarding game, not unlike the Tony Hawk's Underground series or the Skate games that were on the ps3/xbox 360, that takes place exclusively in Japan (*maybe* just in the Tokyo area, as long as Akihabara is a place you can visit). the soundtrack is all j-rock, shoegaze, and anisongs.
...really, i just want a skateboarding game with The Pillows, Mass of the Fermenting Dregs, Coaltar of the Deeprs, and Vocaloid and anisongs as background music, because i think that'd be really cool.
and no, Jet Set Radio Future doesn't count, because it doesn't have anisongs, and it also has a huge emphasis on graffitiing, which doesn't quite fit with what i want here (although, a third Jet Set Radio, or fourth, if you count the GBA game, is also another game i really want...and no, Bomb Rush Cyberfunk doesn't count.)
