This game is a worthey addition to the tony hawks series and i believe gamespot did not review proving ground correctly.

User Rating: 8 | Tony Hawk's Proving Ground X360
I believe this game should of got 8.0 for many reasons.
including the new atmosphere and graphics,new gameplay mechanics including bowl carving,nail the grab/manual and three types of storyline...

Here are the three types of story line which can all be played at the same time.
Career: in this story you focus on money,fame,sponsors etc
you do things like photo shoots (grinding certain tricks down certains rails etc)
for videos you are doing long lines with specific spots and moves.
and in competitions you do things like best combo,massive jumps/gaps
2min runs etc...

rigger:Probably the most dissapointing story line in the game but still fun
at points...this focuses on things like placing rails in places etc and doing trick on/under/over them.

Hardcore:this is skating for fun kind of thing were knowone gets in your way and you will complete missions such as clearing parks of trouble makers etc ...

my favourite part to play would be career because you get to play on mega ramps etc...

one of my small problems with the game is somtimes how badly it tells you how to do goals (ie:hey kid! crooked up this rail and when you almost get to the top nail the trick with one branch 180 and then darkslide back down!)
you do it and it somtimes doesnt notice?

the city to skate in is the best of any tony hawk game buy far with tons of hidden gaps,mini parks etc.

I found project 8 to be much harder than all the other TH games and so is this balancing etc is somtimes really difficullt compared to thug and america wasteland!

in the end proving ground may be difficult to new people to the seires but for peole you have played the game a good bit or non stop they will love it.
