First of all, sorry about my English.
To this day, I completed more than 550 videogames, and with a lot of experience in my pocket, I safe to say Race Driver: GRID is the best racing game I've ever played. When the game released back in 2008, it got high praise by both the critics and the players due to it's innovative gameplay ideas, etc. But GRID 2 and Autosport hammered by a lot of people because these games lost the essential charm that the first GRID has.
To understand the statement above, first you need to know, why the first GRID game is so special. As the wise saw says, the devil is in the detail. There's a lot of small things in the first GRID that create the unique feeling of it. A good example is when you choose your name at the start of the game, then the commentator calls you in your name and he is talking during the race events about what's happening. But I can say something about that fantastic crash modell /physics too. I never seen someting like that since then in any racing game. I remember I spent hours and hours with the GRID demo on my Xbox360 just to constantly amazed by the fantastic crash physics. Then I used the flashback option and it was mindblowing to see that when I turned back time, every little pieces of the car were slowly building back to the car. Sorry, it's hard to say it properly in English, but I hope, you understand, what I'm talking about. These kind of ideas helped the game to create a unique, authentic feeling, and a high level of immersion for the player, and ultimately create that so-called WOW-factor.
So, that WOW-factor is completely missing from GRID 2 and Autosport, because they got dumbed down in a lot of ways, or go wrong in a lot of places. The small unique things from GRID were died when GRID 2 released. Also, the driving mechanics in the first game is unbeleivable enjoyable; it created the perfect balance beetween simulator and arcade style. The feeling of driving in that game is so good. And finally that is the game that get me like the cockpit view, because I can fully control my car and I can play like a pro even if I'm using an interior view.
So what we need? We need a new GRID game with all of the unique things that made the first game great (continuous flashback system, great car handling (simcade style) and crash physics, commentator and "choose a name" option, etc.), and we need some new things too. For example let us play with our friends in two player team in campaign/championship mode.
