Go, now.

Seriously other than Indiana Jones and the Fate of Atlantis and Sam & Max Hit the Road, these are the only point and click games I've ever not only loved but could finish...repeatedly no less.

They're both amazing games (25th is not a port of the NES game) that are written by the old Trek TV writers. Voiced by the original cast. Lots of great things to uncover and do, and if you want you can be a prick and just go off and blow up enemy ships until you get killed as it has a solid combat/repair mechanism to the game too. They're simply amazing games and of course GoG PDF'd the original story books, manuals and star maps too that came with the games.
