Physics: Cross between Heat and N2002. N2002 have always felt like I was
on "Ice", Thunder feels more sticky, but the setup options within the game
affect the cars very similar to N2002.
Damage: More forgiving that N2002
Sound: At times... must give this to N2002, but at others... give it to
Thunder.
Multiplayer: Only joined one race, but it was very smooth play. No warping
at all.
AI: So far, head and shoulders above N2002, but this is VERY early. I hate
N2002 AI BTW :)
Some cool things: You can definately bump a little without spinning out.
You can also get someone loose without spinning them out. They have modeled
this part of the game very well.
Kudos EA
