Okay Okay, I know that I am in a minority here, but I love FMV games. Yes, I know it goes against my usual genre snobbery. Yes, Yes, I know that most of them suck balls. For me, therein lies the charm. It could be that the majority of my infatuation with the adventure genre began to peak with games like Tex Murphy: Overseer, or Gabriel Knight 2. My first experience with FMV was Night Trap on the Sega CD add-on contraption for the Genesis console. Yes...maybe that was the indicator that I would love the FMV cheese. Night Trap was deliciously bad.
Reasons I love it aside, I know that I am not the only one. And here's the site to prove it. FMV World. It's a great site. They have a short synopsis of the known FMV games and a wonderful video section where you can watch intros, cut-scenes, and sometimes full movies made out of the more movie-like games. Back in my day, we had to work for them cutscenes. Now you can get it all at the click of a mouse!
And while I am at it here is a great, more recent Destructoid article on the allure of FMV. There are more articles on FMV World's article page.
