park_84: As a rule of thumb, Win16 games and anything from systems other than PC.
WIn 16 games are all most impossible to run on a 64 bit system, That is why "Indian Jones Desktp Advewntures " wont be here anytime soon.
THe EA Lord Of the Rings games because of license issues. LIcence scpired a number of years ago, EA no longer has the legal right ot sell those. Same for the Dune games.
And then you have games like NOLF which are in licence Limbo.....no one really knows who all the licence owners are;and no one wants to spend the money on legal costs to find out.
Games that caem out for Windows 16 only, dince witout dual boot or VR you cannot run them on a 64 bit Windows system.
I think games like Half Life are very unlikely dut to the policy of the copyright owners, but not totally impossible.
again due to licencing issues.
