"Big idea" + character arc = bingo

I'm definitely always interested with videogame-movie adaptations. I personally play a lot of video games. I heard ladies love it when a guy plays a lot of video games, so thats why keep playin.. hehe.
Most games have a storyline already with-in, but writers will often stray so far from that it feels like they haven't even completed 1 level of the game. Only adaptations i've liked were Resident Evil(1st one) and Silent Hill. I've watched almost all these adaptations, even the Uwe Boll ones. And they all bomb horribly, it definitely inspires me to eventually be one to write these adaptations (and write them well). But until then they just come across as ridiculous jokes for movies.
