Hi, guys!
As a Stunts fan, I'd love to see this. I have a few ideas for it:
Improved graphics: Since you'll be writing it from scratch, why not add some more detail? I'd rather see a successor to Stunts than a remake. Examples are textures (of course), real transparency and maybe soft-body physics like this.
It's going to be a mix of Stunts and Trackmania, so you'll see some improvements...
- textures - yes, on cars and tracks elements...
- real transparency - forget it, it's a mobile game... and any transparency needs double repaint, and down the framerate
- soft-body physics - it's cool thing, but not for now... it's not important for gameplay and we have a lot to do without this cool addition...

Two track editors: I also want a more sofisticated track editor, with more levels, and terrain editor. However, since people also wanted a simpler editor, why not have two of them?
Hahahaaa... may be three? Why not? We have 100 free of work programmers who need to do something... so I'll tell them...

Sorry, but for this game will be only one editor... and no terrain edit abilities... guys, it's mobile game... and we have no budget to make such things, and belive me or not - THIS IS NOT REALLY NEEDED!

Gameplay: One of the ideas in the topic was easier gameplay. I'd say yes, to an extent. Keep all the realism from the PC game, but add more speed tolerance; 40 mph should be ok. Easier handling shouldn't be needed as long as you don't want to use auto-throttle, wich is an absolute no-no.
As I say before... we will make mix of Stunts and Trackmania... no one need car simulator on mobile, 'couse there is no "wheel" or "keyboard" at least - we have stupid "mobile keys" :'(
Single/multiplayer: A multiplayer funtion via bluetooth would be great. However, the game should also have a singleplayer funtion, since you cannot always play against other people.
About bluetooth... we will think. But first is going to be another kind of multiplayer... guess what?

Car names: Regarding names of cars, I think you should keep the old one. I doubt Ferrari or Porsche ever will find about this game, and even if they do, I doubt even Ferrari would care the slightest. At least as long as you keep the game free of charge
Unfortunately I don't believe Netsoftware is developing a free game - it is not much of a viable model for mobile games...
Hmmmm... we plan to release 2 version of game... one, lets call it TM1 - will be free (may be with real cars names, may be not), and second one TM2 will be with sms activation (changed names, but I bet you will recognize em easy...)!
BTW, judging from their Wolfenstein clone I think Netsoftware will do a fair job in improving graphics.
It's not a just a clone, you should play it to see the difference, go
