Neo-Geo AES is a hard one to collect for. I have a boxed system and 14 games....and have spent will over $1000 on it in the years collecting. The cheap games go for $30, the exPensive games go for $300 on up from that. Patience is the key with collecting a system like this. You may go to a convention and be happy with either buying a bucketfull of classic games for other systems, or decide to buy one Neo Geo game. In the end, I would say it is more bragging rights than anything else. Only the insane hardcore collector goes after collecting this one.
