I think the biggest problem of this game is in it's name: if it wouldn't have been called "GRID" it could get away with what it is. But people look at it and expect the experience they had with Racedriver: GRID, which this game doesn't deliver.
First of all, unlike Rd:Grid the game doesn't allow the player to customize his driving experience.
Rd:Grid was like "you wanna play with keyboard? fine, here is a bunch of assists so you can handle the car with those keys. you get better at it, turn some of them off and get extra enjoyment!" or "ofcourse a car would slide, but only if you are not carefull enough with the throttle in the exit of the corner. still cannot tame it? just move the TC slider a little bit backwards". This freedoms resulted in great accessebility and immense fun of driving whatever you input device was.
Instead, GRID 2 says "we got TrueFeel(tm), we have World SIDEWAYS Racing, we are all flashy and hooked up on fans which you gotta impress, so you are going to play the game OUR way!"
Obligatory drifting. Oh gosh, i didn't think i ever see it this series. Thing is, you cannot tell if you are faster without it. It has become part of the game.
Again, comparing to Rd:Grid, sliding the car was never an option if you were going to set a time. You would go for a clean line, resorting to sliding in rare instances, and yet it was fully up to the player. Sliding a corner made you feel "Hahaha yeah!" or "Oops, steady, steady!". GRID 2 does it like "Right, here we go again...".
Not knowing all that, I jumped into it with my itching fingers ready over arrow keys and was for a surprise. "OK, it won't be easy", i thought, and i got better at it, although still failing to have as much fun as i expected. But i kept my hopes up by thinking, "OK, maybe if i get a controller, i might actualy get to enjoy it...". WRONG. No ingame customization for controller device leaves it almost as clunky as keyboard. (to be fair there might be a way to make it better by editing xml file, but that's yet to find out). As it turned out, reading different forums, the game was desigined primarily for full-on steering wheel controllers, walking straight past keyboards and pads like they are history. Only a handfull of those hardcore devices seem to provide a player with full control over the car. Yet in a game, that positions itself as leaning towards arcade driving experience...
Another complaint is the track design. There are not a lot of tracks and locations to choose from. Racing tracks are alright. The trouble hides on city circuits and winding road courses. Like if half-♥♥♥♥♥ controls isn't enough, these end up being littered with hazards, things to hit or send a car flying off the road. Moreover, there simply isn't enough room for 12 hotheads to have their way through, making every game mode a demolition derby. This was not an issue in Rd:Grid.
Coupled with turtle-paced progression of multiplayer, which doesn't reward you for anything besides placing in top 3, you will soon find that if you can't enjoy the driving in this game, there is nothing else left to look for.
