You make a great case. I still love MVP 2005. Played that game more than any other baseball game ever. It does have aspects of it that are just flat out better as I stated before. The area that I love most is fielding and base running. It is the best. Hitting is also really good I agree. The full control of your minor league system is awesome. It is a complete package. But where the show did it for me is the simulation aspect and the hitter/pitcher dual. That aspect of the game for me is unmatched and MVP does not beat it IMO. Hitting is far more of a challenge in The Show. I was a sick hitter on MVP with tough sliders, higher difficulty levels etc. The AI was not as sharp and the hitting was more arcade than sim. MVP pushed the limits of the PS2 no question. Games play and feel more real on The Show.
Now there are things about the Show I don't like and the 2 things that bug me the most are what MVP did the best. Fielding and base running. Because of the clunky controls in that area I have set base running and fielding to auto so I can let the ratings decide those aspects (and the animations just look amazing playing that way) and I focus on pitching and hitting. And it is needed as I am exhausted after 9 innings of The Show.
Both are amazing titles.
