Dude you're comparing apples to oranges. GTA has great graphics.. they have a certain STYLE. It's called ART DIRECTION. GTA5 looks the way it does because that was the art direction for the game. Also, they can go down that route because games like GTA 5 are not trying to replicate something in the real world for authenticity sake.
Bringing up COD, just stop. The graphics arent BAD.. they just don't look any different on next gen than from current gen that much.. but its not like it looked AWFUL on current gen to begin with. So you really need to just stop on the COD thing.. this choice of game was a weak choice to make your point.
Now a SPORTS GAME. I mean one that falls in line with major sports where you are REPLICATING things from the real world.. (players, uniforms, animations, etc) then the quality of the game can factor in the graphics and animations. When you put an NBA or NFL logo on your game to sell it.. and one of the draws to people buying your game is because it's got the same players and teams, and etc etc from the real life counterpart, then you legitimately as a company open the door to be judged on just how close you ARE coming to the real thing. LIVE DOES NOT DO THIS, WHICH IS WHY 99% OF PUBS GAVE IT REALLY LOW SCORES.
To make my point even further.. Look at a game like Hot Shots golf. It's always got great reviews and the graphics don't look realisitc at all.. but they DONT HAVE TO because Hot Shots Golf wasn't slapping the PGA TOUR LOGO ON THE COVER WITH A PICTURE OF A REAL GOLFER.
Make sense or was that over your head?
