Neo Geo has a community of collectors. Because of the limited production runs received by cartridges amongst the sizable available arcade library, some of the rarest Neo Geo games can sell for well over $1,000. The most valuable game is the European AES version of "Kizuna Encounter". The MVS market provides a cheaper alternative to the expensive and rare home cartridges, and complete arcade kits are priced at a premium. It is also possible to play the MVS cartridges, which generally cost much less, on the AES home system through the use of adapters.
