I agree. As much of the state of GT5 now is pretty good, 1.01 was an awful, awful game.
No PP, no seasonals, no leaderboards because no seasonals, no OCD, no gear tuning, worse graphical issues than now, glitches in tracks, no power/weight limits on lobbies, no mechanical damage, no cash or experience from racing online, no Remote Racing (not that anyone cares), no racing gear, no purchasing car parts through the settings screen, worse AI, no mid-race suspend, no "interior" views on standards, no user control of weather, only one setup per car, no FF/RWD in replays, no aftermarket wheels on standards, and a huge number of little bugs fixed by patches over the years.
