I confess to being somewhat underwhelmed by GT4. The cars don't look or sound particularly interesting. It also feels like a confused mash-up of sub-GT3 supercars (AMG, R8, Vantage), small sportscars (570, Alpine, 718) and touring cars (the BMW).
Personally I'd like it to be a series for the smaller, lighter sports cars. It's just too much of a suspension of disbelief to pretend that an AMG, an Alpine and an M4 are all equal! I know this is also true of, for example, a Bentley GT3 vs a Lambo GT3, but GT4 seems to take this to an extreme.
Still, some pretty cars at a pretty circuit on a (mostly) nice day. Enjoy!
