First I don't think people are building up Madden on Ps2, and second, I think it is fair to expect to get more from a game that costs $60 dollars and was designed on newer consoles. Let's look at what I think ps2 did better and/or what I would expect to be better than the game is currently offering.
1. Game modes. PS2 offers a tournament mode with multiple styles of tournies to choose, a fantasy challenge mode, better mini games, deeper franchise mode and superstar modes and EA lockers allowing gamers to take a complete offline franchise online. Current Madden has only Madden moments and MUT, which cost extra. I'd say ps2 has the edge here.
2. Extras that are included. Madden ps2 has create a playbook, and create a play. They allow players to get franchise boosts by collecting Madden cards. When you went online, you got trophies for reaching passing/rushing milestones etc. Current Madden again charges for the boosts and doesn't offer the other features. Again, I think I can give ps2 an edge here.
3. On the field adjustments. Ps2 has individual bump/run shading, and man lock that works well. Current madden's man lock feature doesn't really work properly, but they did add the coverage adjustments for Madden 12. Probably about even in this area, but I certainly wouldn't say Current Madden is better here.
4. Gameplay. This is a bit tougher for me. Current Madden has made a few improvements, but have gone backwards in other areas. There are also problems that ps2 had that I just can't accept in current madden. For instance, run blocking is improved, but ps2 madden has better downfield blocking. Check out this
Tim Tebow vid. At 1:15 Tebow has to blockers leading him to the end zone mirroring his every move. They even turn around at the goaline when he performs a spin move.
Another example is the dbs mirroring routes. It been in both games, but I can no longer accept it in current Madden. Remember
this vid? That looks great and the defender is reacting instead of just knowing where to run. I've seen it done correctly now, so I expect current gen to beat ps2 in the area and it fails right now.
The final area I want to point out is precision passing, vision cone and ball trajectory. The vision cone and passing is preference thing, I know. I prefer the added difficulty it added without forcing me to adjust sliders like I have to now so I prefer the ps2 passing game. I also feel like current Madden should have improved ball trajectory so I can drop passes over an lb. It's a ps2 issue as well, but it's plagued Madden for so long that it's something I feel should have recieved some attention.
5. Finally, presentation. Ps2 is not the benchmark for presentation and it shouldn't be after all these years. The Show and NBA2k show presentation and copmmentary done well. I expect Madden to at least be able to compete in this area and so far it has failed miserable although 12 looks promising.
Sorry for the long rant, but I felt I had to get that off my chest. I hold ps2 in a legendary status and bash current Madden because imo it offered much, much more. Even in areas where current Madden exceeds the ps2, I have seen examples of how it can deliver so much more than it does.
To the OP, I am optimistic Madden 12 will be a solid game but it has a long ways to go just to match what ps2 delivered. Even further to match what other current sports games have done, at least for me.
