@Syxx573@sfamichan The main reason is the limited number of games available. Games featuring anime characters or TV personalities are difficult to re-release.
This is true for any platform, though.
Places that were selling them at high prices from the start will probably still have some in stock. Cheaper places in rural areas have been sold out.
Six stores in my neighborhood are almost completely sold out.
However, CD-ROM software and the consoles themselves are still available.
