I downloaded the update (that also includes the Mercedes cars) and noticed something...
...it sure is nice of them to have already put placeholder "cards" in the character selection screen and level select screen (I just realized I forgot to scroll through the cars), that way you can see the content you
could have but (maybe) haven't bought yet...dangling in front of you like a carrot...or a chocolate cake...teasing you and begging you to buy the DLC! ;-P
If they ever decide to fix battle mode, that had better be free DLC since it shouldn't have sucked so bad in the first place.
I could not agree more...I pretty much hate battle mode on this. I like that there are 12 racers and not just 4 (the last battle mode I played was on the 64...I don't even know if the other games since then have it!), but playing on regular tracks as opposed to in arenas? Not a good choice. I don't know about anyone else, but I spend most of the time just trying to
find someone to hit! I look down at the map to see dirtbag-so-and-so is ahead/behind, then look back up to maneuver up/back to them, don't see them, and look back at the map to see they turned around! "YOU JERK!!"

I want arenas back!
