Lets look at some major fu*k up's, due to good graphics.
MGS-2:A huge hype, orginal was brilliant; put too much work into graphics and they mess it up.
FF-10:Another huge hype, messed up again by trying to show off good graphics. Gameplay sucked harder than a Dyson vacuum cleaner.
Spiderman:The first game on the PS was brilliant, sucked on the PS2.
Munches Oddysee: Wonderful series. Sequel sucked, but had its good points.
Resident Evil 0: Some may argue with this, but alor of fans agree: this prequel sucked.
Well, I'm sure I could go through more. But it seems that sequels that moved on to a next gen console seem to fuck up, because their too busy ''showing off.'' When faced with the graphical dissability of an old console, they concentrait on making the gameplay and story better, such as FF.
It's like movies, the high bidget films just show off. Take Starwars, the originals was fantastic, the sequels just show off. Same went for the Matrix. I'm not a fan of it, but many say the first was better and the sequel sucked--As I noticed, it seemed to be another excuse to show a CG art show.
Though not all games follow this strange path. Take Splinter cell--brilliant! Halo! But, they was fresh onto the next gen console. I think the game developers who created a decent game on a old console allways wanted to go further, so they bring out the sequel... then go too far, untill it becomes a extacy--they can't resist to show a amaizing graphical presentation to wow the audience--unlike before.
