GP2 *is* still king, cos it still does what it was designed to do,
brillaintly. But, a newer modern F1 sim has hit the market called
F1RS by Ubisoft, is just as good (overall) as GP2, and in some areas,
better than GP2, (graphics, newer circuits, teams, weather, etc)
As you may have heard there is also a "retro" F1 sim, called Grand
Prix Legends (GPL) by Papyrus/Sierra based on the 1967 F1 season, and
the game engine, car physics are awesome, better than GP2 & F1RS.
(Only the demo is availabe at the moment, the release date is unknown
but will be around October time?)
