bI think Motorstorm pushed the envelope as well into some extend. There is a reason why we didnt put NFS:Carpon and PGR3 in that list. And thats because they only improved and made even gorgeous the previous effects.
From what I ve seen so far in Motorstorm although the concept isnt any different from previous games, again its the execution in which it pushes the envelope. The AI is trying to resemble as much as possible that of a human. For example, certain types of car may team up to take out a certain smaller type of car. They will also mock you.
Furthermore, the revengful attitude seems more apparent in this one.
1. Never again put NFS:Carbon in the same sentence as PGR3. PGR3 is a quality title, Carbon is typical EA.
2. PGR3 is a semi-realistic street racer, in real life, no humans are going to team up on you and try to take you out when your all driving $300,000 supercars. Nobody will start doing a PIT manuvre with their bentley
PGR3 AI thought, is one of the best racing AI's out there.
3. Some NASCAR games had AI that would ram into you and try to take you out, it wasnt very sophisticated but it was there.
4. Interstate '76 and Carmageddon both had AI that would "take you out", in 1997. Hardly anything revolutionizing
Its simply progress, its not like the team behind motorstorm have made some crazy AI algorythm thats revolutionizing the way we think of gameplay.
And another thing that was really absent previously from other racing games was the ground deformation playing part in the game. Previously it was just a visual treat. Now not only does it looks better than ever, with wet mud deforming and looking as realistic as never before, and different (for once it looks like real wet mad deforming and concentrading water in its bumbs) it affects the handling. Heavy cars deform more than smaller cars the ground and accordingly the handling is supposed to be affected.
So it may not have pushed the envelope greatly enough to make you go WILD, but it pushed it
We have had the technology to do ground deformation in games for quite a while, certain rally titles have had this for a good while aswell. It didnt do anything for gameplay, but it was there, visually (not as good ofcourse). I would say that is simply progress not pushing the envelope...
Of course there are different definitions of pushing the envelope, thats the problem here.
For me, the pushing the envelope is doing something that will in some way change how games are made, played or thought at.
For example, i would say that DOOM1 pushed the envelope, being the first FPS and all that. DOOM 3 just had a new graphics engine.. i would just call that progress. Otherwise, i dont see how you can say that PGR3 is not pushing the envelope, and claim Motorstorm does. Neither does something we havent seen before, but slightly upgraded due to technology advances.
If you can claim that as something else than progress, then i guess every game in the world that does something better than whats allready out there is pushing the envelope.
