I notice the car is a bit slower - so maybe you are right, the car is a bit heavier and some other minor changes
Btw: I ask karjen and he tought it feelt the same ^^
and here is my plus and minus of stadium 2 - happy reading
Lets start with Plus
+ graphic is amazing (eye candy)
+ new cool sound
+ new campaign (65 new thrilling tracks)(official)
+ more players
+ new faster servers
+ new fresh value (Planets)
+ car has slower acceleration
+ get all old stadium maps including united campaign maps for free or almost* (*= You need 5 stations)
+ new easyer map editor with slowmotion and stuff..
+ you can make script (maybe hang man)
+ some minor bug fix
+ create macro block
+ new blocks at release (what i have heard)
+ discover new tmx at MX =
http://mania-exchange.com/ )
+ fresh start in stadium (2)
+ very cheap, 10 euro = (1 or 2 dinners)
+ its also free* - so try it before you buy it

+ low end pc can run it
And now some minus..
- old px tracks are impossible to recreate
- AT - "Author Time" unbeatable on previous stadium campaign
-+ still alot of minor bugs in editor -nadeo working on it (y)
- bugs still exist
I had a great deal of fun with stadium sence i discover it late 2008
I have build about 2000 maps or more.
I hate the bugs in stadium and hope they would have fixed those in stadium2, but i guess players like those darn bugs :/
and with out them, some of my tracks are unfinish able
And Team Nadeo should be proud of there work - you have give me and other much joy true the years ^^
THANKS TEAM - keep on forever.
