The two great late 90's and early 00's FPSes that time forgot! Everything else was remembered from this time period from HL1 to SS2, Deus Ex, etc etc. But these two games were arguably quite great! and were the most forgotten in my opinion. Especially the addon here which was vastly better than the main game. Even less people played it and even less know about it than the main game, which is a shame because it really was an improvement in every way. Fantastic gameplay and level design from this time period. I could add Daikatana to my little list here, but we all know the troubles that had at launch and with the bad AI team mates. Still, another very decent game. However Sin and SoF were the most polished FPS games of this era which were overlooked by most. For some reason. Anyway, well worth a play! And these games are very needing of remakes!
