(Maybe) abandonware games from Matrix Games
 

I surfed through Matrix Games Forum, and i found a topic called "discontinued games". The explanation: Games which are no longer sold or supported, but their forums are kept here for archival purposes. Click on the sub-forum name...

Maybe this games are abandonwares, it's worth to check. Btw i found 3 games which aren't on sale according to the Abandonia's custom google search:

1) Supremacy: Four Paths To Power (Info from matrix games website)
2) Starshatter: The Gathering Storm (Mobygames), Reason: They game cannot be complete without crashing, but this problem was solved by the last patch. Even so the game's distribution was stopped.
3) Reach For The Stars (Mobygames), Reason: The mouse doesn't work on operation systems up from Vista (but on xp and on virtual pc everything is ok).
