Recently, due to the leakage of the source code (200GB) of "GTA5", Rockstar's previous plans have become known to the outside world. For example, the eight story DLCs of "Bully 2" and "GTA5" were all canceled because of "GTAOL". But that's not all of the games that have been canceled by Rockstar. There is recent evidence that Rockstar had developed "GTA: Tokyo" and planned to launch it on PS2, but it was cancelled.
As shown in the picture below, the tipster found keywords such as "Tokyo", "PS2", "model", and "art" in the code, implying that Rockstar had planned to set the stage of "GTA" in Tokyo, Japan a long time ago, but unfortunately it was not implemented.
It is worth mentioning that in 2009, Rockstar launched "GTA: Chinatown" for the PSP and NDS platforms. This may be the first GTA game developed by Rockstar with an Asian protagonist.

In addition to GTA: Tokyo, Rockstar has also canceled Bayside Club 5. This cancellation may mark the end of the series, as Rockstar has been developing new games for more than 15 years.
