Honestly, I don't believe any of the "previews" that I see for games, even if they say "in game footage used". It always ends up that the graphics on the previews are great. Pay $50 for the game, put it in and watch the sweet start up graphics and intro, then hit start to play. Hmmmm....went from sweet hi-def graphics to a lo-res stick figure with a pistol.
Game trailers can also be misleading. I remember the game trailer for guild wars. The game is nothing like the trailer that came out (but guild wars is still a good game!).
They do that so you will buy their game! They only show the 'best' footage, not the in-game stuff. The Final Fantasy series, for example, has some of the best FMV cinemas I've seen...but the in game graphics pale in comparison to games like Shadow Hearts Covenant, or Beyond Good & Evil. Luckily, that's changing (Final Fantasy XII's in-game graphics look pretty good!
), but you can see the marketing scheme to get your cash. Its a slap in the face to the companies that spend lots of time making a game with good graphics, and to us gamers, because they treat us this way ( Marketing guy: "Oh, by the way, the game looks bad in reality; SUCKER! You already bought it!!! *coughlosercough*"
We'll find out in a year or so that it was prerendered.
Most of the PS3 videos at E3 were pre-rendered. They were just showing "what the system could possibly do." We'll see if reality fits the grand promises of the marketing guys.
