So what films are there? Quick summary (and my opinion)
Mario - Hilarious
Mortal Kombat 1 (and 2...ugh) - 1 is actually pretty fun. The sequel...not so much.
Street Fighter: The Game: The Movie - Awful. Utterly horrid.
Double Dragon - Brilliant. I forget the name of the character but the hugely fat guy with the big head..classic
House of the Dead - Uwe Boll shite, complete with scenes from the first two games thrown in.
House of the Dead 2 - Non-Uwe-Boll Shite
Alone in the Dark - Uwe Boll shite where NO-ONE is alone in the dark. Also, invisible lizard creatures and super humans...or something.
Bloodrayne - Should not be paid for, nor watched. Awful.
Dead or Alive - Terrible straight to DVD trash.
Silent Hill - Had promise, ended up comical
Final Fantasy: The Spirits Within - I actually fell asleep during this in the cinema and had a weird dream I was in the film. While they were driving around in the buggy I had a Gorrilaz song stuck in my head.
Resident Evil 1 and 2 - I didn't like them. Stand out daft moments: Kung Fu kicking a dog, riding through a church window on a motorcycle.
Tomb Raider 1 and 2 - Could have been soooo much better.
Doom - Hilarious, actually quite fun with a few drinks and friends round.
Others?
Was there a Wing Commander game? Or TV Show?
I seem to remember a Tekken film, probably animated.
Interestingly checking out imdb gave:
