I was talking about games you posted like Psi-Ops and Area 51 which were once full-fledged retail releases.
Those are freeware releases that were made on purpose by the developers/publishers.http://en.wikipedia....iki/Abandonware
Abandonware is a term used to describe computer software that is no longer sold or supported, or whose copyright ownership may be unclear for various reasons. While the term has been applied largely to older games, other classes of software (such as productivity applications or utility software) are sometimes described as such.
Definitions of "abandoned" vary; generally, it refers to software no longer available for legal purchase, or of a certain age. Software companies may change their names, go bankrupt, enter into mergers, or cease to exist for a variety of reasons. When this happens, product rights are usually transferred to another company that may not sell or support the software acquired.
In most cases, software classed as abandonware is not in the public domain, as it has never had its original copyright revoked. Unlike Freeware or opensource, abandonware is NOT released to be publicly released and company still owns its distributional rights.
Most abandonware sites post/upload games whose companies are no longer active. It's a murky area but 9/10 the games are not really legal and you have to tweak them to work on modern technology.
A good example of what happens with abandonware that sucks is when the company returns and makes all other existing copies of it's product 'illegal.'
Which you are going to see happen more and more with companies like GOG, STEAM, Onlive, D2D and others fighting over publishers/developers libraries in order to boast their numbers of perceived content.
Now when a game is said to be freeware it can not be unsaid (legally) to not be freeware unless the original release of freeware comes with a time stamp...like Farcry, Prince of Persia, Age of Conan...and others.
