That is a very good point. I still play Madden 05/06 on PS2 because the gameplay is great and I like the rosters/rookies on both games.
Yes and that would be combining the best elements of Madden 05 and 06. The reason I play both games is one has certain advantages over the other. For example in 05:
-The overall game/player speed is better. I truly feel this game is still the best video game in representing that aspect of the NFL.
-Pre-game intro/game information and sideline reporter all missing in 06.
-Player faces in 05 were the best on PS2. 06 and onwards everyone looks too similar-like created players.
-Punt returns were better as in 06 it was nonexistant (your players won't block).
-05 has the best CPU gameplay (including next-gen) with the Madden Manifesto.
For 06
-Vision Cone which allows for more realistic completion percentage/accurate representation of reading the defense and going through QB's progressions.
-Pass interference penalty was called. In 05 it was never called even with sliders all the way up.
-Truck stick/Back juke which counteracts the 05 introduced Hit-stick leads to more unpredictable gameplay-in a good way.
-Great WR/DB interaction. As soon as the ball is thrown (especially the deep ball) they both look back to the ball instead of in prior Maddens where the receiver would look at the ball right before the pass can be caught.
-06 playbooks were better especially the running plays. Although 05 was great as well.
That's just some.
I've read that since 07 on PS2 certain running backs get too many carries. I've seen this in 06 but the reason is in the depth chart, 3rd Down Running Back is the same as the starting back which means that back get's all the carries. The way to fix this is to control all 32 teams in franchise and make sure 3DRB and starting back are not the same players or adjust the Coach Option RB2/RB1 slider.
