Intelligentvision is a company which produces original, homebrewn games for the Intellivison. These aren’t shoddy releases by any means however. Excellent, well programmed games, as well as full color packaging are the norm here.
All four games are now on eBay, and going for a hefty price as well. Each game either had 100, 150, or 250 copies made, and all four are long sold out.
Considering these games are only a few years old, it shows one thing – new releases for dead systems are only going to rise in value. So definitely get them at release.
