Nightbreed on the ZX Spectrum. If it weren't for the tiresome cassette loading for each of the game's three main sections, it would easily gone down as one of the greatest Spectrum games of all time. Thank gawd for Speccy emulators! I honestly believed Clive Barker was a games developer for a long while until I realised it was based on a movie which was based on a book he wrote! o_O
Tie Fighter by LucasArts. Bloody awesome game where you join a Grand Admiral called Thrawn to hunt down a traitor fleet led by another Grand Admiral who has decided to wage a technology war against the Emperor. Although you play on the "Dark side", your role is about putting a stop to the traitor fleet's rampage throughout the galaxy. Seemlessly adding in elements from Timothy Zahn's "Thrawn Trilogy" and LucasFilm's Shadows of the Empire media project, Tie Fighter is just a stunning tour-de-force of Space Combat Simulator combined with great atmosphere and story. At a very young age, I felt like I was living a double life of an ace space pilot in a suave galactic navy! Happy days!
SOTN. Went through an emo-stage in my late teens back in the late 90s, while watching too much Interview with the Vampire and The Lost Boys. Alucard is one cool-ass-muddy-funster. Face it, Alucard even dismisses Death's warnings as if he is washing his socks the next day. Would YOU do THAT with a dude dressed in a black robe holding a nasty looking Sythe? Nah, I didn't think so. Not even after 20 years of searching both castles high & low, have I given up the search for that elusive bottle of Old Spice that Alucard has stashed away...I know its there!
Oh, and Metroid is a big thing for me too. Its like going on an adventure with your super cool auntie who plays paint-ball at the weekends with Captain Phasma. I usually let her handle the Metroids though, because they are rather scary! O_O
