I just picked up SiN off of GOG. I think that if it had been properly patched, it could have outdone Half-Life, or at least been a serious contender. The main character is John Blade, who's a sort of Judge Dredd type of guy. He goes after Elexis Sinclaire, who's doing some freaky experiments with people and turning them into mutants. Lots of great gunplay, and even the use of fists, which I enjoy in a shooter. My only problem is that for some reason it never keeps my video options intact when I exit and restart the game. Other than that, A plus!
