GT7 has been simply fantastic thus far. Ignore the ones complaining because they're just upset that they didn't get to play the game for exactly one day. Welcome to live service games, people. Server downtimes are part of it. Given what Polyphony said that update 1.07 had a critical error that could have corrupted save data, I think they made the right call.
Believe me, the reviews would be even worse from the idiots on here if their saved data was lost.
Long story short, this has been one of the best in the series. GT5 was practically a perfect game in every way, but I'd say GT7 is a close second. If you love cars, the history of cars, and the realism, this game is for you. And to address race payout changes that people are upset about, what a shame that you have to PLAY the game to earn rewards. Oh darn.
